Answer:[tex]f^{-1}[/tex](x) = [tex]\frac{x-3}{2}[/tex]Step-by-step explanation:Let y = f(x) and rearrange making x the subjecty = 2x + 3 ( subtract 3 from both sides )y - 3 = 2x ( divide both sides by 2 )[tex]\frac{y-3}{2}[/tex] = xChange y back into terms of x, hence[tex]f^{-1}[/tex](x ) = [tex]\frac{x-3}{2}[/tex]
