I will graph exponential functions using transformations. Part 1: Graphs of the form y=2x +k where k is constant. We call a the base of the function. If we let a =1in f(x) xwe get , which is, in fact, a linear function. As with other types of functions, there is a parent graph for exponential fnctions (y = bX where b is the base) and we can create other similarly shaped graphs using transformations. This graph of an exponential function contains the point (1) 3, 27 . 28. Retrying.
