Q3Multiple correct5 Marks15 Mar 2026Consider the polynomial function p(x)=−(x2−16)(x−3)2(2−x)2(x+9)p(x)=-(x^2-16)(x-3)^2(2-x)^2(x+9)p(x)=−(x2−16)(x−3)2(2−x)2(x+9). Choose the set correct options.Ap(x)p(x)p(x) is strictly decreasing for x∈(4,∞)x\in(4,\infty)x∈(4,∞).BThe total number of turning points is 666.Cp(x)p(x)p(x) is strictly increasing for x∈(−∞,9)x\in(-\infty,9)x∈(−∞,9).DThere are exactly 777 points where the slope is 000.
