Answer :
To find the value of f(4), we simply need to substitute x=4 into the given function f(x) and simplify:
f(x) = (x + 2)²
f(4) = (4 + 2)² [replace x with 4]
f(4) = 6²
f(4) = 36
Therefore, f(4) = 36.
So the correct option is: 36.
f(x) = (x + 2)²
f(4) = (4 + 2)² [replace x with 4]
f(4) = 6²
f(4) = 36
Therefore, f(4) = 36.
So the correct option is: 36.
