Answer:

f(-4)=48

Step-by-step explanation:

<u>Value of functions</u>

To evaluate a function for a given value of x, we replace the x for the value and perform the resulting operations.

The given function is (corrected):

f(x)=-4x+x^2+16

We need to find f(-4), so we use x=-4:

f(-4)=-4*(-4)+(-4)^2+16

f(-4)=16+16+16

\boxed{f(-4)=48}

I really hoped this helped. I'm no genius, but you asked for help and I tried to give it.
Have a great day.
