Given information in attachment, please sketch the graph.
For the rational function f(x) = (x2 - 1) / (x2 - 9), give the interceptsandasymptotesand sketch the graph.
Let f(x)=0, we get x=1 or x=-1. So, the x-intercepts: x=1 or x=-1.
Let x=

1. Give an example of a linear function and show at least one method of graphing it. By looking at the graph of a line, how can you tell if its slope is negative? What kind of line has a slope of zero and why?
2. Give an example of quadratic function and show at least one method of graphing it

1.Find the asymptotes, the interceptsand sketch the following function. A computer sketch is not sufficient. You must explain.For each of the following functions, do a complete analysis: determine the vertical and horizontal asymptotes, and the x and y intercepts; and sketch a graph of the function.
