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
f(x)=-8-5x
[tex]\\ \rm\longmapsto f(-4)[/tex]
- Put -4 inplace of x
[tex]\\ \rm\longmapsto -8-5(-4)[/tex]
[tex]\\ \rm\longmapsto -8+20[/tex]
[tex]\\ \rm\longmapsto 12[/tex]
