Question

Se dau functiile f,g definite pe  R cu valori in R si f(x)=x-5 si g(x)=2x

a) Calculați f(1) , f(2) , f(3) , f(4) , f(5) , f(6) , f(7)
b) g(1) + g(2) + g(3) + g(4) + g(5) + g(6) + g(7)​

Answer 1

Răspuns:

f1= -4

f2= -3

f3= -2

f4= -1

f5= 0

f6= 1

f7= 2

g1= 2

g2= 4

g3= 6

g4= 8

g5= 10

g6= 12

g7=14

2+4+6+8+10+12+14=56
