Question

Determine if the given functions are even, odd or neither.
f(x) = -2x^2 - 7 and g(x) = 2x^2 + 3

A) odd, odd
B) even, odd
C) odd, even
D) even, even

Answer 1

Answer: Choice D
Both functions are even

--------------------------------------------------------------------------

If you graph both f(x) and g(x), you'll see that there is symmetry along the vertical y axis. This is visual proof that the functions are even. For algebraic proof, note how all the exponents are even. For the constant terms, there is a hidden x^0 term so the exponent is even there as well.
