Answer 1

even? @Directrix

Answer 2

I think so but let's get a definition of even function here to verify.

Answer 3

DEFINITION. A function f is even if the graph of f is symmetric with respect to the y-axis. Algebraically, f is even if and only if f(-x) = f(x) for all x in the domain of f. A function f is odd if the graph of f is symmetric with respect to the origin.

Answer 4

f(-x) = (-x)^2 - 3 = x^2 - 3

f(x) = x^2-3

f(-x) = f(x)

Yes, you are correct that the function is even.
