Part a: explain why the x-coordinates of the points where the graphs of the equations y = 2−x and y = 8x+4 intersect are the solutions of the equation 2−x = 8x+4. (4 points)

part b: make tables to find the solution to 2−x = 8x+4. take the integer values of x between −3 and 3. (4 points)

part c: how can you solve the equation 2−x = 8x+4 graphically? (2 points)
