Project 4 MAC 2311 1. Why do we require a > 0 in order for f ( x ) = a x to be an exponential function? Why does every exponential function f ( x ) = a x , a > 0, intersect the y -axis at the point (0 , 1)? 2. How can the graph of the function y = ( 1 2 ) x be obtained from the graph of y = 2 x ? Illustrate by drawing both graphs on the axes below. 3. Carefully sketch the graph of f ( x ) = 1+ e 1 - x below, including any inter- cepts and asymptotal lines, AND state its domain and range in interval notation. Domain: Range: 1
