Answer 1

f(-4) = 37.

Explanation:

We have given the following function:

f(b) = 5-8b

We have to find the value of f(-4).

We have to find the value of function at b= -4.

Putting b = -4 in the function we get,

f(-4) = 5 - 8(-4)

f(-4) = 5+32

f(-4) = 37

f(-4) = 37 is the value of function at b = -4.

Answer 2

f(-4)=37

Explanation:

The given function is

`f(b)=5-8b`

To find f(-4), we substitute x=-4 into the function to get;

`f(-4)=5-8(-4)`

`f(-4)=5+8(4)`

Simplify

`f(-4)=5+32=37`
