Fran graphs the equations y = 2x2 – 2 and y = –0.5x + 4. her graph is shown below. mc010-1.jpg which value is an approximate solution of 2x2 – 2 = –0.5x + 4?

On the added picture you can see that graphs of functions and have two points of intersection. The x-coordinates of these points are the solutions of the equation 
.
Hence, the approximate solutions are x=-1.9 and x=1.6.
