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

There is no B value.
B and b are distinct and different variables.
X and x are distinct and different variables.
Y and y are distinct and different variables.
Variables are case sensitive.
y=a (times) b (to the power of) x
should be written
y=a*b^x
Mathematics is a language with rules just as other languages have rules on how to spell and write them.
