2.(05.03 MC) 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

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

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

Even just one of these would be helpful thx
