Question

Exemplo:
Considere a função f: R R, definida por f(x) = 2x + 1. calcule f(0), f(1), f(-2), f.
f(x) = 2x + 1
f(0) = 2 . 0 + 1 = 0 + 1 f(0) = 1
f(1) = 2 . 1 + 1 = 2 + 1 f(1) = 3
f(-2) = 2 . (-2) + 1 = -4 + 1 f(-2) = -3
f= 2 . + 1 = 1 + 1 f = 2

2.Dada a função f: R R, definida por f(x) = 5x + 2, calcule f(0), f(2), f(-3) e f.​

Answer 1

f(0) = 5.0 + 2 = 0 + 2 = 2

f(2) = 5.2 + 2 = 10 + 2 = 12

f (-3) = 5.(-3) + 2 = -15 + 2 = -13
