Which equation is represented by the graph? a. y=2×^2 - 3b. y=-3×^2 + 2c. y=3×^2 - 2d. y=2×^2 - 2

Hey!

I have attached four different graphs to this answer.

The first graph represents the equation  

The second graph represents the equation .

The third graph represents the equation .

The fourth and final graph represents .

Now, at first I thought the correct answer was graph four, but then I took a closer look at the image you provided and I can tell that that was not the correct answer. You see, both the last to graphs look fairly similar, but they are different by a few points.

Your graph shows two x-intercepts that are not exactly on -1 and 1. Which explains why I though graph number four was the correct answer. But it cannot be the correct answer because graph number 4 shows two x-intercepts EXACTLY on -1 and 1.

So, this means the answer is graph 3, or the equation  .

Hope this helps!

first anwser choice.

step-by-step explanation:

the greater/less or equal to symbol (> or < with the line at the bottom) is a closed/filled in circle.

when multiplying or dividing by a negative on both sides you have to flip the inequality sign. this rule only applies to multiplying or dividing by a negative number in inequality equations. this rule is really important.

-5c + 2 _< _27

subtract from both sides by 2

-5c _< _ 27

divide both sides by -5

c _< _ 5.4

flip the inequality sign

c _> _5.4

the only possible answer that would match the simplified inequality is the first answer choice
