Explain why the negative and positive infinity, respectively. You cannot use a graph (except the basic trig, log and exponential function) or a table of values (you can use direct substitution when appropriately). a) x→−3−lim​x2−9x+1​=−∞ x→−3+lim​x2−9x+1​=∞ b) Based on the results above describe the behavior of the function f(x)=x2−9x+1​ near the point x=−3 c) Draw a sketch of the graph of f(x) for a small neighborhood of x=−3
