Answer:
(fg)(x) = 12x^3 + 9x^2 + 28x + 21
Third option
Step-by-step explanation:
(fg)(x) = (3x^2 + 7)(4x + 3)
(fg)(x) = = (3x^2)(4x) + (3x^2)(3) + (7)(4x) + (7)(3)
(fg)(x) = 12x^3 + 9x^2 + 28x + 21
Fx=5x_ 7/I is a fowards number so say+1 and5x_7= youneed a second number it is2 when u = so 2
X(5-8) would be the answer
