Quizplus · Accepted Answer

The function f(x) = 7|x| + 9x^2 + 1 is even because it satisfies the condition f(x) = f(-x) for all x. The absolute value function |x| is even, and any power of x that is an even number, like x^2, results in an even function. The constant term 1 does not affect the evenness of the function.
