They are called even functions because the functions x 2, x 4, x 6, x 8, etc behave like that, but there are other functions that behave like that too, such as cos (x):
Since the function satisfies the condition f(−x)=−f(x), we classify f(x) as an odd function We know this even before plotting y because the coefficient of the first term, 1 , is positive (greater than zero) Each parabola has a vertical line of symmetry that passes through its vertex.
