C. 6
D. 8

Answer 1

Please help !!

Answer 2

let's call f(x) like y.
So we get: y=4x+1
now soolve for x.
x=(y-1)/4
this is f^-1(y)
for y=3
x=(3-1)/4=?

Answer 3

ups, didnt notice the over 3 part

Answer 4

let's call f(x) like y. So we get: y=(4x+1)/3
now soolve for x.
x=(3y-1)/4
this is f^-1(y)
for y=3
x=(3*3-1)/4=?
