F(x) = 4x + 5
g(x) = x^2 + 4x + 2
Find: f(g(x))

Using substitution, we can substitute the in with . That gives us the equation

Now using the distributive property, you multiply g(x) by 4. This gives us

If you add 8+5, you get 13, giving us our final equation:

hi, i am not sure about this one but i think its d,

hope this !
