Find Domain & Range

Front

What is the domain of a function?

Back

The set of all possible x-values for which the function is defined.

Front

If Li has at most $90 to spend on games costing $22.50 each, what is the domain of the function representing the number of games he can buy?

Back

{0, 1, 2, 3, 4}

Front

What is the range of a function?

Back

The set of all possible y-values that the function can output.

Front

Given the function c = 34.95u + 6.25, where u is the number of uniforms bought, what is the domain if there are at least 8 players but not more than 12 players?

Back

{8, 9, 10, 11, 12}

Front

What does the ordered pair (52, 3) represent in the context of the number of buses needed for a field trip?

Back

52 members require 3 buses.

Front

If the total cost for uniforms is represented by c = 34.95u + 6.25, what is the cost when u = 10?

Back

c = 34.95(10) + 6.25 = 356.75.

Front

What is the significance of the domain in a real-world scenario?

Back

It defines the limits of input values that make sense in the context of the problem.

Front

If the range of a function is all real numbers greater than or equal to 0 and less than or equal to 9, what does this imply about the outputs?

Back

The outputs can be any value from 0 to 9, inclusive.
