Question

Dada a função f(x)=4x-4 determine f (2)e f ( - 1 ) dessa função

Answer 1

bom dia

f(x)= 4x-4  f(2)

f(2)= 4(2)-4

f(2)=4

f(x)=4x-4

f(-1)= 4(-1)-4

f(-1)= -8

Answer 2

f(x) = 4x - 4

f(x) = 4x - 4

x = 2
f(2) = 4.2 - 4
f(2) = 8 - 4
f(2) = 4

x = - 1
f(-1) = 4.(-1) - 4
f(-1) = - 4 - 4
f(-1) = - 8
