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