Concept explainers
To estimate: The year when the amount of fish caught first was greater than 14.5 billion pounds.
Given information:
From 1990 to 2002, the amount of fish F (in millions of pounds) caught for human consumption in the United States can be modeled by
Calculation:
It is known that 1 billion is equal to thousand millions, so
To graph the given function, make a table of values using the given function. Then plot the obtained points and finally connect the points. The table would look like as shown below:
x | |||||
y |
The given function is a 4th degree polynomial with negative leading coefficient, so graph will approach negative infinity as x will approach negative infinity and graph will approach negative infinity as x will approach positive infinity.
Upon plotting all the points and connecting them, the required graph would look like as shown below:
It can be seen from the graph that population would be 14.5 billion pounds approximately 9 years after 1990. Therefore, in the year 1999, the amount of fish caught first was greater than 14.5 billion pounds.
