Which polynomial function is graphed below?

Step-by-step explanation:

We know that the graph passes through the point , since the line crosses the X-axis at , so that means our equation has in it. The graph also passes through the point , so the equation also has in it.

This narrows it down to options C and D.

When a graph "bounces" off the X-axis at a point, like it does at , this is called a "double zero", meaning two factors of the equation equal zero. This means that the graph has , leaving us with option D.

4th option is correct xy=-10

if this was to u plzz mark me the brainliest
