Question

MEDAL AND FAN!! PLEASE HELP! 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 = 4x + 3. Take the values of x between negative 3 and 3.
HERE ARE THE TABLES PROVIDED:
y = 2-^x
_________
