Question

Jika f(x)=x+1 dan g(x)=2x-1. hitunglah a.f(x)+g(x) b.f(x)^2 c.(f(x))^2 d.g(x)^2 e.(g(x))^2 f. f(x):g(x)

Answer 1

(a) f(x) + g(x) = x+1 + 2x-1 = 3x

(b) f(x)^2 = (x + 1)^2 = x^2 + 2x + 1

(c) sama kaya (b)

(d) g(x)^2 = (2x - 1)^2 = 4x^2 - 4x + 1

(e) sama kaya (d)

(f) f(x) : g(x) = x+1 / 2x-1
