Representing Relations and Functions

Front

Is this a function?

Back

No, because 2 has two outputs

Front

Is this a function?

Back

Yes, because all inputs have one output

Front

Is this a function? Options:

No, because 6 repeats itself

,

Yes, because all inputs have one output

,

No, because 2 repeats itself

,

Yes, because all outputs have one input

Back

Yes, because all inputs have one output

Front

Is this a function?

Back

No, because 1 repeats itself

Front

Is this a function? Use the vertical line test.

Back

No, because a vertical line touches more than one point on the relation.

Front

Is this a function? Hint: use the vertical line test

Back

Yes, because a vertical line touches only one point on the relation

Front

Is this relation a function: {(2,3), (4,3), (6,3), (8,5)}?

Back

Yes, because none of the x-coordinates (inputs) repeat itself.

Front

Is this relation a function: {(3,2), (3,4), (5,6), (7,8)}?

Back

No, because the x-coordinate of 3 repeats itself.

Front

What is the domain of the function: {(2,3), (4,3), (6,3), (8, 5)}

Back

2, 4, 6, 8

Front

What is the range of the function: {(2,3), (4,3), (6,3), (8,5)}?

Back

3, 5
