Diketahui f (x)=xkuadrat +5x-3 dan (f-g)(x)=3x+1 tentukan A.g(x) b.f(-1) dan g (-1)

f(x) = x²+5x-3
(f-g)(x) = 3x + 1
f(x) - g(x) = 3x + 1
(x²+5x-3) - g(x) = (3x+1)
(x²+5x-3) - (3x+1) = g(x)
x² + 5x - 3x - 3 - 1 = g(x)
g(x) = x² - 2x - 4

b. f(-1) = (-1)² + 5(-1) - 3
= 1 -5 - 3
= -7

g(-1) = (-1)² - 2(-1) - 4
= 1 + 2 - 4
= -1
