Question

Considere a função f definida por(x)=2x+2 e determine f(-2),+(0) e f(2)

Answer 1

Resposta:

f(x) =2x + 2

Determine f(-2),f(0) e f(2)

f(-2) = 2x + 2

f(-2) = 2(-2) + 2

f(-2) = -4 + 2

f(-2) = -2

f(0) = 2x + 2

f(0) = 2.0 + 2

f(0) = 0 + 2

f(0) = 2

f(2) = 2x + 2

f(2) = 2.2 + 2

f(2) = 4 + 2

f(2) = 6

bons estudos!

Answer 2

Explicação passo-a-passo:

$f( - 2) = 2 \times ( - 2) + 2 \\ f( - 2) = 2 - 4 \\ f( - 2) = - 2 \\ \\ f(0) = 2 \times 0 + 2 \\ f(0) = 2 \\ \\ f(2) = 2 \times 2 + 2 \\ f(2) = 3 \times 2 \\ f(2) = 6$
