Question

URGENTE POR FAVOR!!!!!
f(x)= -4x-1

sendo x= -2, -1, 0, 1 e 2​

Answer 1

Resposta:

f(-2) = 7

f(-1) = 3

f(0) = -1

f(1) = -5

f(2) = -9

Explicação passo-a-passo:

$f(x) = -4x - 1\\\\f(-2) = -4(-2) -1\\f(-2) = 8 - 1\\f(-2) = 7\\\\f(-1) = -4(-1) -1\\f(-1) = 4 - 1\\f(-1) = 3\\\\f(0) = -4(0) - 1\\f(0) = 0 - 1\\f(0) = -1\\\\f(1) = -4(1) - 1\\f(1) = -4 -1\\f(1) = -5\\\\f(2) = -4(2) - 1\\f(2) = -8 - 1\\f(2) - 9$
