Question 13 • PBCSD_Grade_Forgiveness_1200710_Mathematics_for_College_Algebra_S2_2023
A quadratic function is a polynomial whose highest power of x with a nonzero coefficient is 2. In choice B, f(x) = –7x² – x + 2, the highest power is 2, so it is quadratic. Choice A has degree 3, choice C has degree 1, and choice D simplifies to 3x – 3 because 0x² = 0.
