When dealing with synthetic division and it tells you to find P(3) for P(x) =  -whatever equation-  Where do you put the 3 when solving? @ehuman

anonymous · Answer

I never learned synthetic division, I use long division. Sorry

Oh, that's okay. Thank you for all your help in the other problem! Do you know how to find all the zeros of an equation?  @ehuman

anonymous · Answer

yes

nicole143 · Answer

Okay, could you please give me an example of a problem with 4 terms?

anonymous · Answer

In general any value of x causing a numerator to = 0 causes the y to = o so that is an x-intercept. You can have as many as the maximum order for the term.
plugging in 0 for x will solve for the y intercept.
Any x value that causes a denominator to = 0 causes a error or an asymptote.

Okay

anonymous · Answer

in this example, a 3 will cause a 0 in both the numerator and denominator, so it will be an asymptote. you can cancell the like terms as long as you write to the side that x can not = 3
