Question

I don't under stand this question both the equation and the inequality graph the same thing http://imgur.com/HnBtbI6

Answer 1

I checked it out by plugging in the x's and y's from your coordinates for all your points A, B, C, D, E, and F. All the ones that satisfied the inequality just so happened to also be the ones that fell into the curve of the parabola. A and E were the only ones that didn't satisfy the inequality. Try it yourself by subbing in -6 for x and 2 for y in your inequality. That is point A and you will find that it comes to -10 which is not greater than or equal to -8. The next point B, with coordinates of (-4, 0) comes to -4 which is greater than -8. That's how you figure out anything that has an x and a y and some coordinates to go with it; usually it's just a matter of plugging in x and y and finding out whatever it is they are asking you to find out.

Answer 2

@IMStuck Is that only because they were with in the parabola or is that just a coincidence too

Answer 3

No coincidence; it is because they are inside the parabola that they also satisfied the conditions of your inequality.

Answer 4

@IMStuck wow knowing that is gonna make this so much easier thank you so much great help

Answer 5

You're welcome!
