Part a: explain why the x-coordinates of the points where the graphs of the equations y = 4–x and y = 2x + 3 intersect are the solutions of the equation 4^–x = 2^x + 3. (4 points)

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

part c: how can you solve the equation 4^–x = 2^x + 3 graphically? (2 points)
