Answer:

Option C) -51 is correct

That is the evaluated function 5-2[f(-1)]=-51 is correct

Explanation:

Given that the function f is defined by f(x)=-8x+20 and to find the value for the given function 5-2[f(-1)]

First find f(-1) :

Put x=-1 in the function f(x)=-8x+20 we get

f(-1)=-8(-1)+20

=8+20

Therefore f(-1)=28

Now substitute f(-1)=28 in the function 5-2[f(-1)] we get

5-2[f(-1)]=5-2[28]

=5-56

=-51

Therefore 5-2[f(-1)]=-51

Therefore option C) is correct

That is 5-2[f(-1)]=-51 is correct
