i'm having trouble with a problem in my calc class...it isn't really calculus yet since we're still in the review section but it goes somethign like this: ( don't have it in front of me)
a rational function is defined by: R/(x-K) where R and K are constants. find R and K for a function that passes through these two points: (2,5) and i can't remember the other one...but if someone can describe how to do a similar problem or how to go about it that'd be great
PUt in the x,y values. Do it for the next point also. You end up with two equations, two unknowns (R and K). You can solve it.
