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?

Answer :

ok so for part A, the x-coordinate of the intersection is the solution to 2−x=4x+3.
Part B  y>3x+10  for (8,10)
10>3(8)+1010>34
I am not sure about the thrid one
