Part a: 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. part b: make tables to find the solution to 2^−x = 8^x+4. take the integer values of x between −3 and 3. part c: how can you solve the equation 2^−x = 8^x+4 graphically?
