Question

Part A: Explain why the x-coordinates of the points where the graphs of the equations y = 2^(−x) and y = 4^(x + 3) intersect are the solutions of the equation y = 2^(−x) = y = y = 4^(x + 3) (4 points)

Part B: Make tables to find the solution to 2^(−x) = 4^(x + 3) Take the integer values of x only between −3 and 3. (4 points)

Part C: How can you solve the equation 2^(−x)=4^(x + 3)graphically? (2 points)
