Graph the two functions below on the same set of axes.

2 increasing exponential curves, top has asymptote at, y, = 10, graph above the asymptote, passing through the point (0, comma 13). Bottom has asymptote at, x axis, graph above the x axis, passing through the point (0, comma 3).

  1. How do the two graphs compare?

    Look at their y-intercepts.

    The second graph is the first, but shifted units upward.

  2. Suppose the first equation is and the graph is shifted up units. What is the new equation?

    See part (a).
