Question

The points plotted below are on the graph of a polynomial. Which of the following x-values best approximate roots of the polynomial?

Check all that apply.

A. x = 6
B. x = 4.25
C. x = 2.4
D. x = 1.51
E. x = -1.1
F. x = -0.77

Answer 1

Answer 2

I think it might be D.) and E.)

Answer 3

roots mean x-value when y = 0
looks like -1

Answer 4

Im lost?

Answer 5

I thought you connect the dots and then where ever the line passes throught the X-axis is the x value?

Answer 6

Answer 7

@Directrix

Answer 8

yes when f(x) = 0 means crossing the X-axis

Answer 9

hey Directrix he needs help with graphing can you help him?

Answer 10

Just a second.

Answer 11

Find the "dots" on the x-axis or extremely close to the x-axis. They would be roots.

So, x = -1 for sure as somebody already posted.

Answer 12

That's the only one I see. The roots have to have a y value of 0 to get on the x-axis so that the point can be a root.

Answer 13

There is no x = -1 option. The closest option to x = -1 is the E. x = -1.1

Answer 14

As for 1.51 = x, it might be a root but there is a gap between it and the x-axis.
I would not include it. This question is poorly worded in my opinion.
