Q-1: Given the quadratic function: f(x) = y = -x2 - 8x -15 (10 points) (a) Use completing the square method to convert the given equation into the standard form of a parabola with vertical axis. Show all steps. [Hint: The standard form is : y = a(x - h)2 + k, a + 0] (b) Use the result of part (a) to find each of the following. #1. Coordinates of the vertex #2 The equation of the axis #3. Direction in which parabola opens #4. X- intercepts, if any #5. Y-intercept (C) Graph the parabola, showing all the relevant information on the graph
