Question

Let g(x) = x2 + 2 and h(x) = 2x2 - 5x + 11 a) g(4)

Answer 1

Answer:

18

Step-by-step explanation:

$g(x) = x^2 + 2\\\\h(x) = 2x^2-5x + 11$

To solve for g(4) , simply we would need to substitute 4 for x

$g(4)= (4)^2 + 2$

$g(4) = 16 + 2$

$g(4) = 18$

Answer 2

( f + g ) (x) = –2x + 6

( f – g ) (x) = 8x – 2

( f × g ) (x) = –15x2 + 2x + 8
