Question

I need help please :))

Answer 1

To solve for G(f(4))

First replace x with 4 in the equation of f(x), use the solution to replace x in g(x).

F(x) = -4x + 10

= -4(4) + 10

= -16 + 10

= -6

Now replace x in the equation of g(x) with -6

G(x) = x^2 + 7x + 5

= (-6)^2 + 7(-6) + 5

= 36 -42 + 5

= -1

The answer is -1
