To be honest, it's kinda difficult to explain.

ok.... on the graph... put a ruler along or draw the line y = x

so it goes through (0,0), (1, 1), (2, 2)...

find the line that is a mirror image... and thats the inverse function

And go to number 13

I can't get in there because I'm not a Texas student lol.

campbell_st · Answer

so when you have the line.... find  a pair of graphs that are mirror images of each other...

campbell_st · Answer

so if you folded the graph along the line y = x, which pair of graphs sit exactly on top of each other... and thats the answer

anonymous · Answer

There are two problems like that I mean answers

ipwnbunnies · Answer

Yeah, graphically, you can do what campbell is saying. For problems, I believe you exchange x and y, and solve for y.

For example, find the inverse of f(x) = x^2. y = x^2 -> x = y^2 -> y = +/- sqrt(x) 
f^-1(x) = +/- sqrt(x)
