ANSWER
EXPLANATION
The given equation is

We divide through by 4 to obtain;

This can again be written as:

This is the equation of a circle centered at the origin with radius 4 units.
The graph is shown in the attachment.
Answer:
16
Step-by-step explanation:
f(x) = 2x² when x>4
We cannot use this expression of f to calculate f(4)
because ,this expression define f for the value of x
that are greater (not equal) than 4.
………………………………………………………
f(x) = 4x when x ≤ 4 , here x is can be equal to 4
(notice the sign ≤ )
Therefore
f(4) = 4 × (4) = 16
