Question

What are the x– and y–intercepts of the graph of y = x^2 – 10x + 21?

x–intercepts: (–3, 0) and (–7, 0)
y–intercept: (0, –21)

x–intercepts: (7, 0) and (3, 0)
y–intercept: (0, 21)

x–intercepts: (3, 0) and (7, 0)
y–intercept: (0, –21)

x–intercepts: (–3, 0) and (–7, 0)
y–intercept: (0, 21)

Answer 1

x-intercept is when y=0
y-intercept is when x=0
