Question

considere a funcao f(x)=2x+1 e g(x)=x+5.
calcule o valor de f(2)+g(3).

Answer 1

f(x) = 2x + 1
f(2) = 2 . 2 + 1
f(2) = 4 + 1
f(2) = 5

g(x) = x + 5
g(3) = 3 + 5
g(3) = 8



f(2) + g(3) = 5 + 8  = 13

Answer 2

Considere a funcao
 f(x)=2x+1 e g(x)=x+5.

f(x) = 2x + 1
f(2) = 2(2) + 1
f(2) = 4 + 1
f(2) = 5
e
g(x) = x + 5
g(3) = 3 + 5
g(3) = 8

calcule o valor de f(2)+g(3).
f(2) = 5
g(3) = 8
f(2) + g(3) = 5 + 8
f(2) + g(3) = 13
