Explain why the x-coordinates of the points where the graphs of the equations y = 2^−x and y = 8^x+4 intersect are the solutions of the equation 2^−x = 8^x+4. (4 points) Part B: Make tables to find the solution to 2^−x = 8^x+4. Take the integer values of x between −3 and 3. (4 points)

Part C: How can you solve the equation 2^−x = 8^x+4 graphically? (2 points)
