Question

Please help me solve this. I’m really confused on it!

Answer 1

They want you to put your own equation in the box and solve so what you van do is:
f^-1(x)=4x+y
Then plug in the "x" numbers and solve.
(-10)=4(-10)+y
y=30


x y
-10 30
-5 15
0 0
5 -15
10 -30



I hope this helps!!!!!!!!!!!

Answer 2

y will have the same value as x, since if a function f(x) is mapping x onto y then the inverse of f(x) will map y back to x
well, i guess...
