If Fx x 5 and Gx x2 what is GFx A x2 x 5 B x 5 C x2 5

If F(x) = x - 5 and G(x) = x^2, what is G(F(x))? A x^2 + x - 5 B (x - 5) C x^2 - 5 D x^2(x - 5)

Solution

f(x) = x - 5

g(x) = x²

we need to find G(F(x))

G(F(x)) means we will write F(x) in place of \"x\" in G(x).

g(f(x)) = (x - 5)²        // we have substituted \"x - 5\" in place of \"x\" in g(x).
