Below is the graph of f(x) = 2^x. Translate it to become the graph of g(x) = 2^(x-1) + 2.

• Shift the graph of f(x) = 2^x one unit to the right and two units up.

• Shift the graph of f(x) = 2^x one unit to the left and two units down.

• Shift the graph of f(x) = 2^x two units to the right and one unit up.

• Shift the graph of f(x) = 2^x two units to the left and one unit down.
