Part A: Explain why the x-coordinates of the points where the graphs of the equations y = 2^(−x) and y = 4^(x + 3) intersect are the solutions of the equation 2^(−x) = 4^(x + 3).

Part B: Make tables to find the solution to 2^(−x) = 4^(x + 3). Take the integer values of x only between −3 and 3.

Part C: How can you solve the equation 2^(−x) = 4^(x + 3) graphically?
