Unformatted text preview: y & & 4 the y-intercept and y & 2 the horizantal asymptote. Third step changes the signs of y-intercept and horizantal asymptote. The last step makes y & 3 the y-intercept and y & & 3 the horizantal asymptote. It also affects the x-intercepts. The resulting graph is: 6 4 2-2-4-6 3 2 1-1-2-3 x y & 2 f & x /2 ± & 1 Problem 2 (3 pts.) Prove the identity: log a b & ln b ln a Solution. Let’s say log a b & x . We want to show that x & ln b ln a . Follow the steps below: a x & b rewriting log. as exponential ln a x & ln b taking ln of both sides x ln a & ln b use a property of logarithms x & ln b ln a ....
