Step-by-step explanation:
The domain is the span of x-values covered by the function.
From the graph, we can see that the graph covers all the x-values from x=-7 to x=4.
However, note that closed and open circles. There is an open circle at x=-7, which means that the domain excludes x=-7. However, the circle at x=4 is closed, meaning it is included in the domain.
Therefore, the domain is, in interval notation:
We use parentheses on the left because we do not include -7. And we use brackets on the right because we <em>do </em>include the 4.
And in set notation, this is:
Answer:
A. 1,825 days
B. 56 days
C. 1 week
D. 1,209,600 seconds
E. 43,200 seconds
F. 2 hours
Step-by-step explanation:
A. 1 year = 365 days, then
5 years = days = 1,825 days.
B. 1 week = 7 days, then
8 weeks = days = 56 days.
C. 7 days = 1 week.
D. 1 hour = 3,600 seconds, then
336 hours = seconds = 1,209,600 seconds.
E 12 hours = seconds = 43,200 seconds.
F. 3,600 seconds = 1 hour, then
7,200 seconds = hours = 2 hours.
