Question

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

Answer 1

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...

Answer 2

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!!!!!!!!!!!
