SP3 Unit I: Graphing exponential functions and identifying x-intercept, y-intercept, asymptotes, domain, range





 Identify all parts of the equation (a,b,h, and k) and know how they affect your graph. So understand that "a" shows that the graph will be below the asymptote and "b" shows that the asymptote is at -2. The viewer needs to pay special attention to the x-intercept. You cannot take the log of a negative number. Thus, it is undefined and you have no x-intercept. Make sure you input your equation correctly into your y= screen. Use your table to plug in the x-values that will give you a more accurate sketch of the graph and obtain the values for your key points. Remember "The EXPONENTIAL YaK Died."- exponential graphs have an asymptote of y=k, leading to no restrictions on the domain. For the range, go from the lowest most negative point up to the asymptote, -2.
