Question 1149768: How do I find the points for an inequality y is greater than or equal to x squared minus 8.
I know that it is a parabola which opens upwards with a vertex of -8.
The program we use only allows for whole numbers to be selected and therefore finding x and y intercept by setting one variable to zero does not work.
