Use the graph of y = x2 - 6x to answer the following:
a) Without solving the equation (or factoring), determine the solutions to the equation x^{2} - 6x = 0 using only the graph.
b) Does this function have a maximum or a minimum?
c) What is the equation of the line (axis) of symmetry for this graph
d) What are the coordinates of the vertex in (x, y) form?
