The graph of the equations y=x^ + 4x-1 and y + 3 = x are drawn on the same sat of axes. At which point do the graphs intersect?

1) (1,4) 2) (1,-2) 3) (-2,1) or 4(-2,-5)

I missed the lesson when we were learning this, can someone help?
 
??

what do yo umean incomplete, thats the question!!! ill write it again

The graph of the equations y=xsquared + 4x-1 and y + 3 = x are drawn on the same sat of axes. At which point do the graphs intersect?

The tutor means just that. You had earlier written "x^ + 4x - 1", which means "x to some unspecified power, plus 4x, less 1". This is incomplete. You have now written "xsquared", usually formatted as "x^2". This is the rest of the information that the tutor requested.

Please do not be offended when the tutors request the complete statement of the exercise. They aren't in your class, so there is little they can do in the way of an answer when you have not yet provided them with a clear question. I apologize for any confusion.

Meanwhile, what have you done so far? Where does it look, from the graph you did, that the curves intersect?

Thank you.

Eliz.

P.S. Please stop posting the same exercise to multiple categories and in "private messages" to the tutors. Thank you.
 
OK, you are NOT winning friends. You MUST learn to be more cooperative and live by the rules. You must not post the same question multiple times. Quit it. You have been given several hints on how to proceed. You deleted some of them. This has become more of a behavior problem than a math problem. Please fix it.

Now, answer the questions you have been asked.

Your problem statement was not initially complete. You have fixed it, now. Good.

You must have other instructions. How are you to find the intersection?

Draw the graphs and look?
Substitute and do the algebra?
Use the given points until you find one?

It is time for you to start acting better. let's learn some mathematics and leave the social issues to another forum.
 
SRY I JUST STARTED THIS, AND I DIDN'T KNOW YOU COULDN'T POST SOMETHING MORE THAN ONCE sorry for the capslock. I am not sure how to graph the equation, thats why i need help ok???
 
Very good. You have provided additional information. That is what is needed.

Sadly, if you truly have no idea how to graph a line, you are struggling at a different level than can be examined by the answer to this problem statement. A nice sit-down with your teacher is in order. Perhaps some schedule adjustments could be made.

no i understand kind of how to graph a line, you start on the y intercept, than you go to the left or right and down or up depending on your slope. Then you conect the points, and you extend your line as far as possible, and put arrows at the end.

So it's just the quadratic you're having trouble with...? The lessons (links provided earlier) should suffice. Please study them and then graph the quadratic equation on the same axes as you graphed the linear equation. Looking at the completed graph should enable you easily to answer the exercise: just copy down the intersection point's coordinates.
