Answer:


f(-4)=48

Explanation:

Value of functions

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}
