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). (4 points)

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. (4 points)

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