Question

Is this an odd, even, or neither. Why?
f(x)=Square root of 1+2x^2

Answer 1

\[\sqrt{1+2x^2}\]

Answer 2

it is even if f(x) = f(-x)

Answer 3

try plugging in x = 2 and x = -2

is the function the same value for each of these values of x?

Answer 4

If "yes," then the function is even. Otherwise, it is not, and may be "odd" or "neither."
