se considera functia f: RR, f(x)= x+2 sa se calculeze f(0)+f(1)+...+f(2012) ​

Answer 1

Răspuns:

2029104

Explicație pas cu pas:

f: R ----> R, f(x)= x+2

f(0)+f(1)+...+f(2012) ​= ?

--------------------

f(0) = 0+2 = 2

f(1) = 1+2 = 3

f(2) = 2+2 = 4

..........

f(2012) = 2012+2 = 2014

f(0)+f(1)+...+f(2012) ​= 2+3+4+.......+2014=

= (2+2014)·(2014-2+1):2 = 2016·2013:2 = 2013·1008=

= 2029104
