Tolong donkk yg baik... Diketahui f(x)=5x+2 dan g(x)=x²-5 Tentuka rumus. A.(gof)(x) B.(gof)(x)

f(x) = 5x + 2
g(x) = x² - 5

a). f o g(x)
f o g(x) = f(x² - 5)
f o g(x) = 5(x² - 5) + 2
f o g(x) = 5x² +23

b). g o f(x)
g o f(x) = g(5x + 2)
g o f(x) = (5x + 2)² - 5
g o f(x) = 25x² + 10x - 1

Semoga membantu ✔
