Question

doar ex 2 imi trebuie va multumesc

Answer 1

Răspuns:

2.a)(f•f)(x)=f(f(x))=f(2x)=2×2x=4x

(f•f•f)(x)=f(f(f×)))=f(f(2x))=f(4x)=2×4x=8x

(f•f•f•f)(x)=f(f(f(f×))))=f(8x)=2×8x=16

.

.

.

( f•f•...•f)(x)=2×nx

b)(g•g)(x)=g(g(x))=g(2x+5)=2(2x+5)+5=4x+15

(g•g•g)(x)=g(g(g(x)))=g(4x+15)=2(4x+15)+5=8x+35

(g•g•g•g)(x)=g(g(g(g(x))))=g(8x+35)=2(8x+35)+5=16x+75

.

.

.

(g•g•...•g)(x)=2[nx+5(n-1)]+5

Sper ca te-am ajutat!
