Question 909355: Hi. First of all I'm not so sure if this problem goes here but it is for functions and their graphs. I have been looking for help on this problem for hours but it just doesn't make sense anymore and this is my last resort. "Let P= (x,y) be a point on the graph y= 1/x.
a. express the distance d from p to the origin as a function of x
b. use a graphing utility to graph d=d(x)
c/ for what values of x is d smallest?"
Do I have to use any formulas or anything, I am so sorry for asking.
