Question

If f(x) = -8 - 5x, what is f(-4)

Answer 1

Answer:

f(- 4) = 12

Step-by-step explanation:

To evaluate f(- 4) substitute x = - 4 into f(x) , that is

f(- 4) = - 8 - 5(- 4) = - 8 + 20 = 12

Answer 2

f(x)=-8-5x

$\\ \rm\longmapsto f(-4)$

• Put -4 inplace of x

$\\ \rm\longmapsto -8-5(-4)$

$\\ \rm\longmapsto -8+20$

$\\ \rm\longmapsto 12$
