1. In Exercises 21 - 26, graph the function. Find the slope, y-intercept and x-intercept, if any exist. Use some additional/different points than the solutions 2.1 #21 and 23 wk 3 f(x) = 2x 1 f(x) = 3 2. solve the equation analytically wk 7 6.4 #15 and 17 log3 (x 4) + log3 (x + 4) = 2 log169(3x + 7) log169(5x 9) = 1 2 3. use the six-step procedure to graph the rational function. Be sure to draw any asymptotes as dashed lines. #7 4.2 f(x) = 4x x 2 +4 Steps for Graphing Rational Functions Suppose r is a rational function.6 STEPS 1. Find the domain of r. 2. Reduce r(x) to lowest terms, if applicable. 3. Find the x- and y-intercepts of the graph of y = r(x), if they exist. 4. Determine the location of any vertical asymptotes or holes in the graph, if they exist. Analyze the behavior of r on either side of the vertical asymptotes, if applicable. 5. Analyze the end behavior of r. Find the horizontal or slant asymptote, if one exists. 6. Use a sign diagram and plot additional points, as needed, to sketch the graph of y = r(x). log 169 ( 3 x +7 )log 169 (5x-9)=12
