Three quadratic polynomials and three descriptions of parabolae are given below. Polynomials: P1(x)=2x2−8x+6P_{1}(x)=2x^{2}-8x+6 P2(x)=−x2−2x+3P_{2}(x)=-x^{2}-2x+3 P3(x)=x2+4x+7P_{3}(x)=x^{2}+4x+7 Descriptions of graphs: (i) Match each polynomial to the correct description A, B or C. (ii) For every match, justify your choice by referring to appropriate algebraic features of the polynomial.
