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

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

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