For the quadratic function f(x) = x2 - 6x, answer parts (a) through (c). (a) Graph the quadratic function by determining whether its graph opens up or down and by finding its vertex, axis of symmetry, y-intercept, and x-intercepts, if any. Does the graph of f open up or down? O up O down X What are the coordinates of the vertex? 20 -16 -12 - 8 8 12 20 The vertex of the parabola is . (Type an ordered pair. Use integers or fractions for any numbers in the expression.) What is the equation of the axis of symmetry? The axis of symmetry is (Type an equation.) What is/are the x-intercept(s)?
