Question

Can someone help me please

Answer 1

solve for x and reverse the variables....

y=(4x-3)/8 multiply both sides by 8

8y=4x-3 add 3 to both sides

8y+3=4x divide both sides by 4

(8y+3)/4=x so

f(x)^-1=(8x+3)/4

Answer 2

y = (4x-3)/8
8y = 4x - 3
8y+3 = 4x
(8y+3)/4 = x

f^-1(x) = (8x+3)/4
