Question

If f(x) = 5x − 3, which expression represents its inverse function?

x+3/x+2

x+3/5

5/x+3

x-3/2

Answer 1

first use this identity f(x) = y

so we have
y=5x-3
next swap the x and y
then solve for y
finally replace your new y with \[f^{-1}(x)\]

Answer 2

a?

Answer 3

just to check

y = 5x - 3

ok swap the x and y
