Diketahui f(x) = x + 5,g(x)=2x + 3 dan h(x) = 3x - 1 . tentukan (f °g) ° h(x)

Langsung aja y

misal → (fog)(x) = s(x)

(fog)(x) = f{g(x)}

= g(x) + 5
= 2x + 3 + 5
= 2x + 8

(soh)(x) = s{h(x)}

= 2h(x) + 8
= 2(3x-1) + 8
= 6x - 2 + 8
= 6x + 6

semoga berguna +_+

(f°g)°h(x) = (f(g(x)))°h(x)
(f°g)°h(x) = f(2x+3)°h(x)
(f°g)°h(x) = (2x+3+5)°h(x)
(f°g)°h(x) = (2x+8)°(3x-1)
(f°g)°h(x) = 2(3x-1) + 8
(f°g)°h(x) = 6x-2+8
(f°g)°h(x) = 6x+6
