Question 730922
What is the exponential function (y=ab^x) whose graph passes through the points of (-1, 48) and (2, 6).
------
You have 2 equations to solve for a and b.
---
48 = ab^-1
6  = ab^2
-----
Divide and solve for "b":
8 = b^-3
b = 1/2
----
Solve for "a":
6 = a(1/2)^2
6 = a/4
a = 24
-----
Equation:
y = 24(1/2)^x
