#11 REASONING Is the x-intercept of the graph of y = ax2 always 0? Justify your answer. yes;
A. The x-intercept of every quadratic function is 0.
B. no; The graph of a quadratic function can have either one or two x-intercepts anywhere on the x-axis.
C. yes; The x-intercepts are the x-values where y = 0, and in a quadratic function a cannot be zero. So y = ax2 = 0 only when x = 0.
D. no; The value of a can vary, so the graph might not have an x-intercept.
