Question

if F(x)=3x-2 and G(x)=x^2+8 what is G(F(x))?

Answer 1

first find f(x) .. it's 3x-2 and now we should find g(3x-2)

Answer 2

g(y) = y^2 + 8 and now we have to substitute 3x-2 in place of y so it would be :\(\Large \color{lime}{ (3x-2)^2 + 8} \)

Answer 3

got it?

Answer 5

G(F(x))=(3x-2)^2 +2
=9x^2-12x+6
