Question

F(x)=-5x^2+4x-9 g(x)=8x^2-3x-4 find (f+g)(x)

Answer 1

To find (f+g)(x), add the given functions f(x) and g(x).

Step-by-step explanation:

To find (f+g)(x), we need to add the given functions f(x) and g(x).

(f+g)(x) = f(x) + g(x)

According to the given functions, f(x) = -5x² + 4x - 9 and g(x) = 8x² - 3x - 4.

Adding the two functions, we get:

(f+g)(x) = (-5x² + 4x - 9) + (8x² - 3x - 4)

= -5x² + 4x - 9 + 8x² - 3x - 4

= 3x² + x - 13
