In general, if you take a function and replace the x's with (x - h) you move the graph to the right h units. And if you take a function and replace it's y's with (y - k) then you move the graph up k units.

In your problem . If we replace the x with (x-2) we get the function e^(x-2) and the graph this function is the same as g(x) except it is 2 units to the right. If we take g(x) and replace it's y (or g(x)) with (y - 3) (or (g(x) - 3) we get . Then if we add 3 to both sides we get and the graph of this new function is 3 units up from the original g(x).

Combining both we see that f(x) = e^(x-2) + 3 will have a graph which the same as g(x) except it has been moved 2 units to the right and 3 units up. The graph below is close to the being your problem. (Algebra.com's graphing software will not graph e^x so I used 3^x.)
