Identifying the values a, b, and c is the first step in using the Quadratic Formula to find solution(s) to a quadratic equation. What are the values a, b, and c in the following quadratic equation? 18 = −9x + 7x2

A. a = 18, b = 9, c = −7

B. a = 18, b = −9, c = 7

C. a = 7, b = 9, c = 18

D. a = −7, b = 9, c = 18

If g(x) is an odd function, which function must be an even function?
