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?
