Answer:
y = 11·10^x
Explanation:
The two points give rise to two equations in 'a' and 'b'.
y = ab^x
11 = ab^0
1100 = ab^2
__
We can simplify the first equation to ...
11 = a
Dividing the second equation by the first gives ...
100 = b^2
10 = b . . . . . take the square root
The exponential function is ...
y = 11·10^x
