Plot the y-intercept and the roots. Click on the graph to plot a point

-2,2

I'm sorry, but I am unable to plot points or provide a graph as a text-based AI. However, I can help you understand the concept.

The y-intercept is the point where a function or equation crosses the y-axis. In this case, the y-intercept is when x = 0.

To find the y-intercept, you can substitute x = 0 into the equation and solve for y. If you provide the equation or function, I can assist you further in finding the y-intercept and roots.
