Answer:

y = 0.2·0.5^x

Explanation:

An exponential function is generally of the form ...

y = a·b^x

where 'a' is the function value when x=0, and b is the ratio between values for x=1 and x=0.

In the given table, y = 0.2 for x = 0, so a = 0.2.

We find that the value for x = 1 is 0.1, so the value of b is ...

b = 0.1/0.2 = 0.5

Then the exponential function is ...

y = 0.2·0.5^x
