Sketch a function

There are many possible graphs you could draw. Put dots in a few appropriate places, and some lines in the right direction at the ends, and then fill in between using some imagination. Then show us your idea, and we can tell you what improvements might be needed, if any.

I'm not completely sure about this but plz feel free to explain how to do it and the correct answer plz. I tried drawing arrows on both side but if I draw arrow on left side than it would be negative infinity so should I draw arrow up

I only see one x-intercept; where are the other two?

You do need an arrow on the left, so it doesn't just stop. If it should go to +infinity, up seems like the way to go! But this looks to me like it says negative infinity:

​

And are you doing this?

​

Does "maximum and minimum" in your class refer to a local (relative) max and min, or absolute? If it means the latter, the problem is faulty!

One more thing: it looks like a vertical line at the right, which wouldn't be a function!

There should be three x-intercepts at x = -4, x = 1 and x = 3.

Please show those.

Sketch a function

Recall a function that has 3 roots. That might help.

Can you plz draw out the graph for me on how u would do it. Plz just attach a picture
I draw one to infinity and one to negative infinity.
Plz feel free to attach youtube videos tht will help me tysm.

Plz draw me a graph to use as reference ty

Do you know the definition of x-intercept?

There should be three x-intercepts at x = -4, x = 1 and x = 3.

Please show those.

Please plot those points on the graph.

Here is an example of this sort of problem. The following graph has x-intercepts at -3, -1, and 3; and as [imath]x\to\infty[/imath], [imath]y\to-\infty[/imath], while as [imath]x\to-\infty[/imath], [imath]y\to\infty[/imath]. It also has a (local) maximum and minimum. Do you see all of these things?



Your graph lacks both the correct intercepts and the correct end behavior. Do you see that?

Your graph, of course, only needs to be a sketch, and doesn't have to be smooth.

You are given 3 points and end behavior.
You need to know what an x-intercept is. You need to look up the definition! You were taught this in basic algebra, intermediate algebra, trigonometry and precalculus.
Armed with this you should be able to draw a function. I suspect, based on your graph, you need to look up the definition of a function. Functions too were taught to you in basic algebra, intermediate algebra, trigonometry and precalculus.
