Question

mathmale · Answer

Let me ask you a few questions first.
In these problems, what does "end behavior" mean?

How does the graph of y=x^2 behave if you start with negative x and move to the right towards positive x?

anonymous · Answer

It increases right?

mathmale · Answer

No.  Please draw the graph of y=x^2 and then try again to answer my 2nd question.|dw:1411864430298:dw|

mathmale · Answer

"increases" partially right, but you will see why "increases" is not the correct response if you're able to draw the graph of y=x^2 properly.

Something like that, hqar

mathmale · Answer

Good enough.  Now, describe the behavior of the function as you go from x=-5 towards x=0.  Next, describe the behavior as you from 0 to +5.

anonymous · Answer

Both increasing? -5 to 0 is increasing, right? and 0 to +5 is increasing.

mathmale · Answer

Hint:  the function is increasing as soon as you pass x=0 going to the right.
Try again.

anonymous · Answer

I'm lost, is -5 to 0 Decreasing?

anonymous · Answer

And 0 tp +5 increasing?
