The number of trout in America since 2000 is given by the following formula:

"x" is the number of years and "y" is the number of trout in the millions.
Based on this formula, estimate the number of trout in the years 2005, 2010, and 2015.

Describe the trend in the number of trout as the years increase.

See below

Step-by-step explanation:

Given formula

Year 2005, finding number of trout

Year 2010, finding number of trout

Year 2015, finding number of trout

Number of trout is trending up with significant increase over yeas

Step-by-step explanation:

Number of trout in 2005.

Find the number of years apart from 2000 to 2005.

2005 - 2000 = 5

Substitute for x and solve for y.

y = x² + 3x + 2

y = (5)² + 3(5) + 2

y = 25 + 15 + 2

y = 40 + 2

y = 42 million

Number of trout in 2010.

Find the number of years apart from 2000 to 2010.

2010 - 2000 = 10

Substitute for x and solve for y.

y = x² + 3x + 2

y = (10)² + 3(10) + 2

y = 100 + 30 + 2

y = 130 + 2

y = 132 million

Number if trout in 2015.

Find the number of years apart from 2000 to 2015.

2015 - 2000 = 15

Substitute for x and solve for y.

y = x² + 3x + 2

y = (15)² + 3(15) + 2

y = 225 + 45 + 2

y = 270 + 2

y = 272 million
