Answer:
Even
Step-by-step explanation:
A function is called even if, for all values of x, f(-x) = f(x).
A function is called odd if, for all values of x, f(-x) = -f(x).
If none of these equalities is satisfied, the function is neither even nor odd.
In this question:
g(x) = 4x² + 3
g(-x) = 4(-x)² + 3 = 4x² + 3
Since g(-x) = g(x), the function g is even.
