Question

Complete the following sentence:You can verify the zeros of the function y=x2+6x-7 by using a graph and finding where the graph _________
A. is at a minimum

B. is at a maximum

C. crosses the x-axis

D. crosses the y-ax

Answer 1

You can verify the zeros of the function y=x2+6x-7 by using a graph and finding where the graph  C. C. crosses the x-axis . Finding the zeros mean equating the equation to 0 or y =0. When y =0, this is equal to x-axis. C. is the answer to the problem given above.
