## Math = Love: Algebra 2 Interactive Notebook Pages for Unit 1

I haven't yet figured out a way to introduce these notations without overwhelming my students. They had to write the domain and range in both interval and algebraic notation. However, just as zero does not have a reciprocal, some functions do not have inverses. It's available from Amazon, comes in loads of colors, and is priced very reasonably. We can visualize the situation as in. I told them that they just had to wait.

## Answers to Questions on Finding Inverse Functions

Then, on the second day we created a foldable to summarize what we had discovered on the previous day. Your simple foldables which I am a huge fan of have put a lot of the ideas into an easy to understand format that just might help me get through this math class. Have your students turn to the page and read the definition. Keep up the great work! Each row or column of inputs becomes the row or column of outputs for the inverse function. I'm hoping to get some online organizing done this summer. We are also learning how to use the graphing calculator. As a heater, a heat pump is several times more efficient than conventional electrical resistance heating.

I think this is a big improvement over the coordinate plane foldable I did with my students last year. Verifying That Two Functions Are Inverse Functions Suppose a fashion designer traveling to Milan for a fashion show wants to know what the temperature will be. Do you have any plans to show how you would organize other Algebra 2 units? You can email me at mbsawyer08gmail. The foldable is made to perfectly hold our domain and range practice cards that are housed in the envelope. This is both exciting and kinda terrifying. Our first unit in Algebra 2 is an introduction to functions, function notation, domain and range, intercepts, maximums and minimums, intervals of increasing and decreasing, finding solutions, and transformations. I still have to figure out how I want to introduce transformations to my Algebra 2 students.

I have looked over the blogpost over and over, but I do not see the download for the cards you used. But, we used them a lot, so I think it was worth it. The If a horizontal line intersects the graph of a function more than once, then it is not one-to-one. I have posted the rest of my Algebra 2 units on my blog as well. By the way, thanks for the shoutout on the envelope. .

However, I like the pockets you can put in binders, so I have students use a cardstock copy of the formula sheet that is allowed on our state End of Course Test, and create a pocket folder on the inside front cover with it. If the graph goes approaches negative or positive infinity, the students leave the flap open where it reads positive or negative infinity. In these cases, there may be more than one way to restrict the domain, leading to different inverses. Domain and Range Foldable That sadly doesn't photograph well. Jonell Wilson I just found your blog!!! He is not familiar with the Celsius scale. Can you teach {insert other math class here} next time? Since we have only just started exploring functions in general, the examples we went through were quite simplistic. I have some students who are complaining right now that Algebra 2 is too easy.

## Spring Notes

I absolutely love your blog! My advice - spend lots of time modeling how the notebooks can be used as a reference. When I had asked my students to draw a table, she had taken this to mean a literal table. Section Exercises Verbal Each output of a function must have exactly one output for the function to be one-to-one. Determining whether or not a function is one-to-one is important because a function has an inverse if and only if it is one-to-one. At the end of the year, students were able to easily find and distinguish between the three variables that indicate transformation. Are there math teachers who don't like math? To travel 60 miles, it will take 70 minutes.

Hi, Sarah, great job with this unit. If the original function is given as a formulaâ€”for example, y as a function of x â€” we can often find the inverse function by solving to obtain x as a function of y. Thank you again and again! My goal is to create a foundation which I can build off of once we start linear functions. Of course, I like math. Functions where each value in the range corresponds to exactly one value in the domain. The check is left to the reader. Posts may occasionally contain Amazon Affiliate Program links.

Is there a way you could send me the cards? Before they knew it, we would be exploring logarithms, exponentials, conic sections, and all kinds of other exciting mathematical relations. I am a middle school special education teacher who is only teaching math this year, which is quite possibly my least favorite subject-- though my kids can relate to the fact that I struggled with math during middle school. We can use this function to convert 77Â°F to degrees Celsius as follows. The interpretation of this is that, to drive 70 miles, it took 90 minutes. This year, I am not teaching directly to the Common Core State Standards. In 60 minutes, 50 miles are traveled. Recall that a function is a relation where each element in the domain corresponds to exactly one element in the range.
