Best ResponseYou've already chosen the best response.1No, the first one is not correct, didn't check the rest.

Best ResponseYou've already chosen the best response.1One check you can do yourself for checking inverse functions is to plot a few points of the original function and a few of the inverse. The inverse function will be an exact replica of the original reflected across the line \(y = x\) (just a line extending up and to the right at a \(45^\circ\) angle). I have plotted your answer here so you can see that it is not correct:

Best ResponseYou've already chosen the best response.1No, (a) is not correct either. Can you show me how you are doing this?

Best ResponseYou've already chosen the best response.0my teacher just told us that you would need to make everything opposite?

Best ResponseYou've already chosen the best response.1Oh, it's an expensive program called Mathematica. There are undoubtedly many cheaper or free options, this just happens to be the one I have at hand. You could also use graph paper and pencil :) Uh, that's probably not exactly how they put it... Let's say you want to find the inverse of \[f(x)=3x+2\]First, replace \(f(x)\) with \(y\): \[y = 3x+2\]now switch the two variables. anywhere you see \(y\), you put \(x\) and vice versa. \[x = 3y+2\] now solve that for \(y\) and you have your inverse function \[x2=3y\]\[y = \frac{x2}{3}\]

Best ResponseYou've already chosen the best response.01+x/4=y is what i got but it can also be the same thing as d right?

Best ResponseYou've already chosen the best response.1ah, yes, that's better. you need to write that as \[(1+x)/4 = y\]if you are going to write it all on one line like that

Best ResponseYou've already chosen the best response.1by the rules of operator precedence, \[1+x/4 = y\] is the same as\[1 + \frac{x}{4} = y\]

Best ResponseYou've already chosen the best response.1So yes, (d) is the correct answer for the first part. Unfortunately, you probably realize that you did 2 of the others incorrectly...but got the 3rd one right.

Best ResponseYou've already chosen the best response.1(to be clear, 3rd one is referring to Question #3)

Best ResponseYou've already chosen the best response.0#1. D #2. idk how to do that one? #3. D #4. C Are they correct now and can you help me on question 2?

Best ResponseYou've already chosen the best response.1Ok, for 2, we have to first find the inverse function, then evaluate it at \(x=9\) What is the inverse function of \(y = 6x3\)

Best ResponseYou've already chosen the best response.1sorry, I looked too quickly at your answer for #3, that's not correct...but we'll work through it and get the right one.
