Answer:

(f - g)(x)  = -x³ -5x² + 4x + 14

Step-by-step explanation:

        f(x) = 2x³ - 3x² + 5

       g(x) = 3x³ + 2x² - 4x - 9       subtract

(f - g)(x)  = (2-3)x³ + (-3-2)x² + (0 - -4)x + (5 - -9)

(f - g)(x)  = (-1)x³ + (-5)x² + (0 + 4)x + (5+ 9)

(f - g)(x)  = (-1)x³ + (-5)x² + (4)x + (14)

(f - g)(x)  = -x³ -5x² + 4x + 14
