Question

Daca f:R cu valori in R si f(x)=2x-1, calculați f(0)+f(1)+...+f(10)​

Answer 1

F(x)=2x-1

x=0

F(0)=2x0-1=-1

F(1)=2x1-1=1

f(2)=2x2-1=3

f(3)=2x3-1=5

f(4)=2x4-1=7

f(5)=2x5-1=9

f(6)=2x6-1=11

f(7)=2x7-1=13

f(8)=2x8-1=15

f(9)=2x9-1=17

f(10)=2x10-1=19

f(0)+f(1)+....+f(10)=-1+1+......+19=99
