Shift the graph of 3 x y = down one unit. 5.1.17 Use the graph of 3 x y = and transforms to sketch the exponential functions. Determine the domain and range. Also, determine the y-intercept and find the equation of the horizontal asymptote. Objective 3: Solving Exponential Equations by Relating the Bases The function ( ) x f x b = is one-to-one because the graph of f passes the horizontal line test. If the bases of an exponential equation of the form u v b b = are the same, then the exponents must be the same. The Method of Relating the Bases for Solving Exponential Equations If an exponential equation can be written in the form u v b b = , then u v = . 5.1.23, 26, and 30 Solve the exponential equation using the method of relating the bases by first rewriting the equation in the form u v b b = ....
