The function f represents the diver's distance from sea level over time, in seconds.
To find:
The correct statement for the domain.
Solution:
Domain is the set of input values for which the function is defined.
Here, x values are the input values and they represent time intervals on which the function is defined
Here, the possible intervals for x are .
Therefore, the domain is the time interval (−9, 7). Hence the correct option is A.
Answer:
B
Step-by-step explanation:
the mean is calculated as
mean =
this year's mean = =
= 4.1
last year's mean = =
= 3.1
difference = 4.1 - 3.1 = 1
