Question

Which of the following equations would have 2 -intercepts?

Answer 1

C, x^2 - 4

Explanation:

both a and b have the vertex on the x intercept, as they have no y transformations. only c has a y transformation, telling us that it is possible to have two points on the x intercept. To solve for the two points, plug in 0 for y. 4 = x^2, so the two points would be 2 and -2.

Answer 2

Explanation:

I think it is that none of the choices are correct, because when you graph them, you get a parabola. Parabolas only have ONE y-intercept, so you can be sure that none of the answers are correct.
