Answer:

Step-by-step explanation:

so to go forward we input x and get out y,   to go backwards ( the inverse) we plug in y and get out x   ,  so just solve the equation for x

f(x) = 8x - 5

remember that f(x) = y

so,

y = 8x - 5

now solve for x

y+5 = 8x

(y+5) / 8 = x

then remember that we want to swap x and y ,

(x+5) / 8 = y

now y = [tex]f^{-1}[/tex](x),  it's kinda confusing.

 [tex]f^{-1}[/tex](x)= [tex]\frac{x+5}{8}[/tex]
