Question

If f(x)=x²-16 is continuous at x = -4, find f(-4).

Answer 1

Answer:

0

Step-by-step explanation:

f(-4) means x = -4 so then plug -4 into the function.

y = -4²-16

y = 0

Answer 2

Answer:

f(-4) =0

Step-by-step explanation:

f(x)=x²-16

Let x = -4

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

       =  16-16

       = 0
