jika f(x) = 2x-3 dan g(x)= x²+2x-3, maka nilai dari (fog)(2) =

(fog)(x)=f(g(x))
=2(x^2+2x-3)-3
=2x^2+4x-6-3
=2x^2+4x-9

(fog)(2)=2(2)^2+4(2)-9
=8+8-9
=7

f(x) = 2x - 3
g(x) = x^2 + 2x - 3

(f○g)(x) = f(g(x))
= 2(x^2 + 2x - 3) - 3
= 2x^2 + 4x - 6 - 3
= 2x^2 + 4x - 9
(f○g)(2) = 2(2^2) + 4(2) - 9
= 2(4) + 8 - 9
= 8 + 8 - 9
= 7
Jadi nilai dari (f○g)(2) adalah 7
