Answer:

The Given situation is In 2005, the shabelle river in Somalia rose an estimated 5.25 inches every hour for 15 hours.

Increase in water level is represented by the function,f(x)=5.25 x.

or replacing f(x) by y we get ,y= 5.25 x

This is equation of straight line passing through the origin.

As x is number of hours , so x> 0,(0,∞] Which is it's domain.

As x> 0, so Range is those values of y for which x is defined.

x= \frac{y}{5.25},So Range is y>0 i.e (0,∞}

As the function has no breaking point , that is when you plot the graph on coordinate axis there is no breaking point.So , it is everywhere continuous i. e for all values of x.

A country clerk has given amount of money to budget for cultural events
Neko [114]

Answer:

A. the total amount of the budget given to the country

Step-by-step explanation:

In order to know the answer, you have to check what the<em> y-axis</em> represents. In the graph above, it represents the "Budget Remaining," which is expressed in <em>thousands of dollars. </em>On the other hand, the<em> x-axis</em> represents the "Time," which is expressed in<em> months</em>.

Point (0,18) shows the total amount of the budget for the Cultural Events in the country. It starts at 18,000 dollars and decreases as months pass by. This is shown by the graph's <em>"negative slope."</em> This means that<u> as the number of months increases, the amount of money decreases.</u>
