Diketahui fungsi f(x)=5x-1 dan g(x)=5x²+6.Nilai dari komponen fungsi (gof) (1) =......

5(5x–1)² + 6 = 5 (25x² –10x + 1) + 6
= 125(1)² – 50(1) + 5 + 6
= 75 + 5 + 6
= 86

Diket: f(x) : 5x - 1
g(x) : 5x^2 + 6

Ditanya: (gof) (1) : ?

(gof) (x) = g(f(x))
g (5x - 1)
5(5x - 1)^2 + 6
5(25x^2 - 10x + 1) + 6
125x^2 - 50x + 5 +6
125x^2 - 50x + 11


(gof) (1) = 125(1)^2 - 50(1) + 11
125(1) - 50(1) + 11
125 - 50 + 11
86
