If the parent function f(x) = x2 is modified to g(x) = 2x2 + 1, which statement is true about g(x)?
A. It is an even function.
B. It is an odd function.
C. It is both an even and an odd function.
D. It is neither an even nor an odd function.
f ( x ) = x² ( the parent function ) f ( x ) is an even function. g ( x ) = 2 x² + 1 g ( - x ) = 2 ( - x )² + 1 = 2 x² + 1 Answer: A ) It is an even function
