Recall that the graph of a quadratic function is represented by the equation: y = axz + bx + c The table that follows represent the coordinates of three points that lie on the graph of an unknown quadratic function. x 3" 1 2 1 4 2 4 (a) Use the three given coordinates to construct a 3 x 3 system of linear equations in variables a , b and c. [6 rnks] (b) Solve the system for variables a, b and c . [8 rnks] {c} Hence, find the quadratic function y = (11:2 + bx + r: that passes through the given points. [1 mk]
