Question

If g(f(x))=
${x}^{2} + x - 2$and
$\frac{1}{2} (g(f(x))) = 2 {x}^{2} - 5x + 2$
then f (x) is?​

Answer 1

Answer:

Step-by-step explanation:

if g(f(x)) = x^2 + x - 2 then

(1 / 2)(g(f(x))) = x^2 / 2 + x / 2 - 1

So your supposition that

(1 / 2)(g(f(x))) = 2 x^2 -5 x + 2

does not make sense.
