Question

2- Dada a função f(x) = -2x + 5, determine:
a) f(1) =


b) f(0) =


c) f(-2) =


d f(-4) =
​

Answer 1

Resposta:

Explicação passo a passo:

f(x) = -2x + 5, determine:

a) f(1) => f(x) = -2x + 5 => f(1) = -2(1) + 5 => f(1) = -2 + 5=> f(1) = +3

b) f(0) =>  f(x) = -2x + 5 => f(0) = -2(0) + 5 => f(0) = 0 + 5=> f(0) = +5

c) f(-2) =>  f(x) = -2x + 5 => f(-2) = -2(-2) + 5 => f(-2) = +4 + 5=> f(-2) = +9

d f(-4) =>  f(x) = -2x + 5 => f(-4) = -2(-4) + 5 => f(-4) = +8 + 5=> f(-4) = +13
