How do we work out question 18. PLEASE explain

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

Write an equation for the function that includes the points (2,100)and (3,100)
