Domain and Range Practice (2024)

Front

What is the definition of 'Domain' in a function?

Back

The domain of a function is the complete set of possible values of the independent variable (input) for which the function is defined.

Front

What is the definition of 'Range' in a function?

Back

The range of a function is the complete set of possible values of the dependent variable (output) that results from the function.

Front

Given the function c(u) = 34.95u + 6.25, what is the domain if u represents the number of uniforms bought for a volleyball team with 8 to 12 players?

Back

The domain is {8, 9, 10, 11, 12}.

Front

If a plumber charges $80 plus $45 per hour, what is the range of the cost for a maximum of 8 hours?

Back

The range is 80 ≤ y ≤ 440.

Front

What is interval notation for the range [-4, 5]?

Back

The interval notation is [-4, 5].

Front

What type of data is represented by the average speed of a car (e.g., 72 m.p.h.)?

Back

Continuous data.

Front

What type of data is represented by the number of players on a volleyball team?

Back

Discrete data.

Front

What is the formula to calculate the total cost of hiring a plumber for x hours?

Back

The formula is y = 80 + 45x.

Front

What is the maximum number of hours a plumber can work in a day according to the given scenario?

Back

The maximum is 8 hours.

Front

If the domain of a function is {0, 1, 2, 3}, what does this imply about the function?

Back

It implies that the function is defined only for these specific input values.
