Question

If Fx) = 2x-3 5 which of the following is the inverse of F(x)?

Answer 1

`\begin{gathered} f(x)=(2x-3)/(5) \\ y=(2x-3)/(5) \\ x=(2y-3)/(5) \\ cross\text{ multiply} \\ 5x=2y-3 \\ 2y=5x+3 \\ divide\text{ through by 2} \\ y=(5)/(2)x+(3)/(2) \\ f^(-1)(x)=(5)/(2)x+(3)/(2) \end{gathered}`

The answer is B.
