Question 13 • DHS Algebra 2 V

How would you explain the relationship between the real zero(s) of the function and x-intercept(s) of the graph?

Answer

A

Since the graph crosses the x-axis at x = – 2, the function has a real zero of x = – 2.

B

Since the graph never crosses the x-axis, the function has no real zeros.

C

Since the graph eventually crosses the x-axis, the function has a real zero.

D

Since the graph crosses the y-axis at , the function results in a real zero of x = ?.
