Review: Domain & Range of Linear Functions

Front

What is the domain of a function?

Back

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

Front

What is the range of a function?

Back

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

Front

In the function p=12t-240, what does 't' represent?

Back

The number of t-shirts sold.

Front

Is the function p=12t-240 continuous or discrete?

Back

Discrete.

Front

What is the domain of the function p=12t-240 when t represents the number of t-shirts sold?

Back

D: {0, 1, 2, 3,...40}.

Front

What is the range of the function p=12t-240 when t is in the domain {0, 1, 2, 3,...40}?

Back

R: {-240, -228, -216,...240}.

Front

What is the domain of the set of ordered pairs: (2, 11), (9, -3), (7, 21), (-8, 6)?

Back

D: {2, 9, 7, -8}.

Front

What is the range of the set of ordered pairs: (2, 11), (9, -3), (7, 21), (-8, 6)?

Back

R: {-3, 6, 11, 21}.

Front

If a function is defined as f(x)=30+12.5x, what does 'x' represent?

Back

The number of people ordering the meal.

Front

What is the domain of the function f(x)=30+12.5x if there are 15 people?

Back

D: {0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15}.
