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

Part B: Make tables to find the solution to 4^-x = 2^x + 3. Take the integer values of x between -3 and 3.

I have no idea to do any of that

I think you're just supposed to make a table of values for each function
and graph them... and see where they intersect

Oh ok, and for the second part of B where it says "take the integer values....." is that a restriction of some sort?
