Question

PLEASE HELP!!! Which Equation is represented by the graph?

A. y=2×^2 - 3

B. y=-3×^2 + 2

C. y=3×^2 - 2

D. y=2×^2 - 2

Answer 1

Hey!


I have attached four different graphs to this answer.

The first graph represents the equation
`y=2 x^(2) - 3`

The second graph represents the equation
`y = -3 x^(2) +2`.

The third graph represents the equation
`y= 3 x^(2) -2`.

The fourth and final graph represents
`y=2 x^(2) -2`.

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
`y= 3 x^(2) -2`.

Hope this helps!
