Question

How do I find the inverse of
f(x)= 3x+15 over -17x-16

Answer 1

if it has an inverse; just solve it for the "x" variable

Answer 2

y = f(x) = 3x+15 / -17x-16

y = 3x+15 / -17x-16

y(-17x -16) = 3x+15

-17xy -16y = 3x+15

-17xy -3x = 16y + 15

x(-17y -3) = 16y + 15

x = f(y) = 16y+15 / -17y-3
