Answer:
[tex]f(-4)=48[/tex]
Step-by-step 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):
[tex]f(x)=-4x+x^2+16[/tex]
We need to find f(-4), so we use x=-4:
[tex]f(-4)=-4*(-4)+(-4)^2+16[/tex]
[tex]f(-4)=16+16+16[/tex]
[tex]\boxed{f(-4)=48}[/tex]
