1.) What do we mean by the degree of a polynomial, and what role does the degree play in finding asymptotes for rational expressions?
2.) Explain the relationship between an equation in exponential form and the equivalent equation in logarithmic form.
 3.)  How do the graphs of exponential and logarithmic functions differ?  
4.) Given a rational function, identify a method which can be used to determine if there is a vertical asymptote.
