Question

anonymous · Answer

Any help would be great. I'm so close to finishing this assignment and going to bed...

imstuck · Answer

It's D because to find an x intercept, you replace the y with zero.  The same goes for finding y intercepts...replace the x with a 0.

imstuck · Answer

Only one 0 appears in the y column, so there is only one x intercept.

anonymous · Answer

But it's a continuous function.

anonymous · Answer

Because it's continuous, it leads me to believe it's not C or D.

Look at how y changes in sign when you go from x = -3 to x = 0

Then it changes in sign again when you go from x = 0 to x = 1

jim_thompson5910 · Answer

This function is continuous, so it has to cross over the x axis at some x value between -3 and 0 (and again between 0 and 1)

anonymous · Answer

So it definitely has more than one x-intercept?
