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

part b: make tables to find the solution to 4x = 2x−1. take the integer values of x between −4 and 4. (4 points)

part c: how can you solve the equation 4x = 2x−1 graphically? (2 points)
