Answer and maybe an explanation.Thanks in advance.
inversessolve for xreplace x with f inversereplace y with xso first minus 2 both sidesy-2=√(2x-3)square both sidesy^2-4y+4=2x-3add 3 to both sidesy^2-4y+7=2xdivide both sides y 2(y^2-4y+7)/2=xx turns to f inverse and y turns to xf(x)⁻¹=\(\frac{x^{2}-4x+7}{2}\)looks like they didn't want to expand the binomialy=\(\frac{(x-2)^{2}}+3}{2}\)answer si A
