Question

Using the graph, determine the coordinates of the roots of the parabola.

I really don't understand how to do this because I have never been taught this before. Could someone help me out?

Answer 1

Answer: (-6,0) and (-8,0)

!!!!!!Also it's fixed now so ignore my comment about this being wrong!!!!!!

Explanation:

To find roots you're basically looking for the points on the graph where they touch the x axis. Those are your roots. You can also plug 0 and -0 in for x and find the coordinates that way with the equation.

Answer 2

Two points.

(-8, 0) and (-6, 0)

Explanation:

The roots of a graph are another word for the zeros of a graph. In other words, the roots or zeros of a graph are whenever the graph touches or crosses the x-axis. Another way to think about roots are that the roots of a graph are simply its x-intercepts.

From the graph, we can see that it does this twice: once at
`x=-8` and again at
`x=-6`. At both of these points, the graph crosses the x-axis.

Therefore, we will have two roots in this case: one at (-8, 0) and another one at (-6, 0).

So, our answer is two points, being: (-8, 0) and (-6, 0).

And we're done!
