Explain the effect f (x) + k has on the graph if the exponential function f (x) Be specific and use complete sentences for full credit.

The + k part of the function takes the original function and translates it straight up k units. It's as simple as that. If your function is the line f (x) = 3x, then the function f (x) = 3x + 4 moves that first function up 4 units.
