Intro to Functions (Algebra 1)

Front

Is this a function or not?

Back

Not a Function

Front

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

Back

{-4, 0, 1, 3}

Front

Is the relation a function? Why? Options: Yes, because the x-value 11 has two y-values pair with it., Yes, because each x-value has only one y-value paired with it., No, because the x-value 11 has two y-values pair with it., No, because each x-value has only one y-value paired with it.

Back

No, because the x-value 11 has two y-values pair with it.

Front

For the function {(0, 1), (1, -3), (2, -4), (-4, 1)}, write the domain and range. Remember: Domain is x and range is y (x,y)

Back

D:{0, 1, 2, -4} R:{1, -3, -4}

Front

What is the range of the following relation: (9, -2) (4, 3) (8, 10) (-4, 8)

Back

{-2, 3, 8, 10}

Front

Define a function in mathematical terms.

Back

A function is a relation where each input (x-value) has exactly one output (y-value).

Front

What is the domain of a function?

Back

The domain of a function is the set of all possible input values (x-values) for that function.

Front

What is the range of a function?

Back

The range of a function is the set of all possible output values (y-values) for that function.

Front

Give an example of a function.

Back

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

Front

Give an example of a relation that is not a function.

Back

The relation {(1, 2), (1, 3)} is not a function because the x-value 1 has two different y-values.
