Question 1101634
So, the formula is y=a (times) b (to the power of) x 
My table is:
FOR X: FOR Y:
-2 8
-1 4
0 2
1 1 
Can you help me find the B-value please? 
Formula:: y = a*b^x
Solve for "b" using the points (-2,8) and (-1,4):
8 = ab^-2
4 = ab^-1
----------
Divide the top equation by the bottom equation to get:
2 = b^-1
Then b = 1/2
