Find the inverse function of f

Question

Find the inverse function of f

f(x)=8x+6

Answer 1

f(x) = 8x + 6 = y

switch x and y to get

x = 8y + 6, solve for the new y

8y = x-6

y = (x-6)/8 = f^-1(x), the inverse of f(x)

where f(x) added 6, the inverse subtracts 6, where f(x) multiplies by 8, the inverse divides by 8
