Diketahui f(x) = x2 dan g(x) = x + 4. Tentukan: a. (f + g)(–3) c. (f × g)(–1) b. (f – g)(1) d. f g ⎛ ⎞ ⎜ ⎟ ⎝ ⎠ (2)

a.) (f+g)(-3) = (-3)2 + (-3)+4 = -5
b.) (f-g)(1) = (1)2 - (1+4) = -3
c.) (f×g)(-1) = (-1)*((-1)+4) = -3
yang d soalnya di hp munculnya kotak2 jd gajelas. tp semoga membantu yaa

a. (f+g)(x) = x²+x+4
(f+g)(-3) = (-3)²+(-3)+4 = 9-3+4 = 10

b. (f-g)(x) = x²- (x+4) = x²-x-4
(f-g) (1) = 1² - 1 - 4 = 1-1-4 = -4

c. (fxg)(x) = x²(x+4) = x³+4x²
(fxg)(-1) = (-1)³+4(-1)² = -1+4 = 3
