I have a question
what type of graph would this sketch?
y=(x-1)(x+4)
_____________
(x-2)(x+3) |

Parabola, I think. What the heck is that second equation? Is that your signature!?  _________________

its to show that the first set of x's is over them. |

Parabola.
If you distribute you would get x^2 + 3x -4 so it would be a parabola.
It opens upward and its bottom tip is in the 3rd quadrant. Hope this helps....man I can't believe I remember Calculus lol....its been like 3 years haha |

Something really close to this:
My paint abilities are THROUGH THE ROOF!! LMAO
Have you learned the FOIL method? Multiply the first terms(x*x), the outer terms(x*4), the inner terms(-1*x), and the last terms(4*-1). That what you needed to know? _________________

I know foil
do i do it to each set? and will that give me the amount of boxes that should be inbetween the lines? |

Yup, do it to each set. Not really sure what you're looking for, but you can do it by hand with "plug and chug". Pick an x value, plug it into the equation, and find the y value. You'll notice at x=2 and x=-3 you can't solve, and that's where the asymptotes are. _________________

Ok enough! I know for a fact that there are forums for smart people who want to play with calculus and othe things ridiculous! Stop making us all look like dummies will ya'll!  _________________ Rob Gray

Aww come on Deriann, all you have to do is take the derivative of the integral to achieve the equation of the function and then you can graph it using a table which will tell you where all critical points, asymptotes, and concavity are!  _________________

You would use the foil method. F (First) O (Outside) I (Inside) L (Last).
So you would multiply X times X and get X^2 (first term in each parenthesis), then you would multiply X times 4 and get 4x (Outside terms in each parenthesis), then you would multiply -1 times X and get -1x (Inside terms in each parenthesis), then you would multiply -1 times 4 and get -4 (Last terms in each parenthesis).
So once that is done it gives you X^2 + 4x -1x -4 and you would combine like terms in the center and finish with X^2 +3x -4
Hope this helps |
