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. (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)

triciaal · Answer

hint: if a = b and b = c then a= c 

if 10= 6 + 4 and 10 = 8 + 2 
10 = 10
 therefore  6 + 4 = 8 + 2 

here y  = y solve for x

triciaal · Answer

the intersection is when the (x, y) for one graph is same for the other  we already equated the "y's"

triciaal · Answer

for part B do you know how to do the table?
