Question

Which pair of functions are inverses?a. f(x) = 2, g(x) = -2 c. f(x) = -x + 3, g(x) = x - 3
b. f(x) = x2 , g(x) = x - 3 d. f(x) = x + 1, g(x) = 2x - 2

Answer 1

a. f(x) = 2, g(x) = -2 c. f(x) = -x + 3, g(x) = x - 3
b. f(x) = x2 , g(x) = x - 3 d. f(x) = x + 1, g(x) = 2x - 2

Answer 2

you know how to find inverse...
which one troubles you ?

Answer 3

I dont see where I plug it in

Answer 4

OH
I FEEL STUPID

Answer 5

neverrrrrmindddddd

Answer 6

you would have swap the variables and solve for y

Answer 7

so, you did figure out all of them ?

Answer 8

dont feel stupid :P

Answer 9

a quick way would be to plug in a test number but then it could also be the danger that the test point will work but it wont be an inverse function
