Answer:
y = 0.2·0.5^x
Step-by-step 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
Answer:
B.
Step-by-step explanation:
Although the numbers given are negative, we can see that by the lines surrounding them, it is asking for their absolute value. Since absolute values are always positive, the correct answer would be B.
