Function Flashcard

Front

What is the domain of the function {(0,1), (1,-3), (2,-4), (-4,1)}?

Back

D: {0, 1, 2, -4}

Front

What is the range of the function {(0,1), (1,-3), (2,-4), (-4,1)}?

Back

R: {1, -3, -4}

Front

What is the range of the function represented by the interval [150, 275]?

Back

The range is [150, 275].

Front

Which set of values represents a function? (9,5) (10,5) (9,-5) (10,-5), (3,4) (4,-3) (7,4) (3, 8), (6,-5) (7, -3) (8, -1) (9, 1), (2, -2) (5, 9) (5, -7) (1, 4)

Back

(6,-5) (7, -3) (8, -1) (9, 1) is a function.

Front

Does the table with repeated x-values represent a function?

Back

No, there is a repeated x-value.

Front

Is the graph a function or not a function?

Back

Not a Function.

Front

Define a function in mathematics.

Back

A function is a relation that assigns exactly one output for each input.

Front

What is the difference between domain and range?

Back

Domain is the set of all possible input values (x-values), while range is the set of all possible output values (y-values).

Front

What does it mean for a relation to be a function?

Back

A relation is a function if no two ordered pairs have the same first element (x-value).

Front

What is an example of a function?

Back

f(x) = 2x + 3 is a function because each x-value has a unique y-value.
