Diketahui f(x)=2x-5 dan g(x)=x2+3x-4.tentukan (g°f)(x)

Diket :
f(x)=2x-5
g(x)=x²+3x-4

Dit :
(g°f)(x)

Jawab:
(g°f)(x) = g(2x-5)
            = (2x-5)² + 3(2x-5) -4
            = 4x² - 20x + 6x - 15 - 4
            = 4x² - 14x -19

semoga membantu :)

Dik :
f(x) = 2x - 5
g(x) = x^2 + 3x - 4
Dit : (g o f) (x)..?

Jawab :
(gof) (x) = (2x-5)^2 + 3(2x-5) - 4
(gof) (x) = 4x^2 - 20x + 25 + 6x - 15 - 4
(gof) (x) = 4x^2 - 14x + 6
