Part A: Explain why the x-coordinates of the points where the graphs of the equations y= 4^x and y = 2^x-1 intersect are the solutions of the equation 4^x = 2^x-1. (4 points)

Part B: Make tables to find the solution to 4^x = 2^x-1. Take the integer values of x between -4 and 4. (4 points)

Part C: How can you solve the equation 4^x = 2^x-1 graphically? (2 points)
