Question 5 The graph of the quadratic function f(x)=(æ – 2)(r + 8) intersects the y-axis at (0, c). The vertex of the function is (-3, – 12.5). The equation f(r)= 12 has two solutions. The first solution is a= -10. Let T be the tangent at z = -3. a. Find the value of c. b. Write down the equation for the axis of symmetry of the graph. c. Use the symmetry of the graph to show that the second solution is = 4.
