Question

Please i really need help, i really need this i will give a brainliest to the people that answer correctly

Answer 1

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]

Answer 2

B

Hope this helps!
