NEED THESE ASAP I have no idea what this is

When the solutions to each of the two equations below are graphed in the xy-coordinate plane, the graphs of the solutions intersect at two places. write the y-cordninates of the points of intersection in the boxes below in order from smallest to largest. y=2x y=x^2-3

The roots of the function f(x) = x2 – 2x – 3 are shown. what is the missing number?
