ALGEBRA 1, SEMESTER 2What is the average rate of change of the function over the interval x = 0 to x = 8?

f(x)=2x+3/3x−3
Enter your answer, as a fraction

Answers

Replace X with 0 and solve the equation, then replace x with 8 and solve the equation again.

Then find the difference between the 2 answers and divide that by the difference in the 2 X values.:

f(0) = 2(0) + 33(0) -3 = -3

f(8) = 2(8) +33(8) - 3 = 16 + 264 - 3 = 280-3 = 277

Difference: 277 - (-3) = 277+3 = 280

Difference between the X values 8 - 0 = 8

Average rate of change: 280 / 8 = 35

The number of T-shirts a basketball team orders depends on the number of players on the team. **Remember: THE OUTPUT depends on THE INPUT

Answers

The total of T-shirts is proportional to the total of players, which means 15 players = 15 t-shirts.

What is a proportion?

A proportion describes the number of elements from one category compared to the number of elements in another. For example, if there are 15 boys and 15 girls in a classroom the number of girls and boys is proportional.

How are the number of t-shirts and players related?

These have a proportional relationship because for every player it is expected there is a determined t-shirts number and this number can only increase if the players increase.

1 t-shirt per player:

36 players = 36 t-shirts

2 t-shirts per player:

36 players = 72 t-shirts
