List the ordered pairs

(-1, 1), (-2, 1), (-3,2), (-4,2)

Determine if the relations is a function and describe the pattern

Yes it is a function, input goes up 1 and output goes up by 15

Yes it is a function, input goes up 15 and output goes up by 1

Not a function, input goes up 1 and output goes up by 15

Not a function, input goes up by 15 and output goes up by 1

Determine if the relation is a function

No, each input is the same as the output

What is the definition of function?

Every input has only ONE output

Inputs have different outputs every time

Yes, because all inputs have one output

Yes, because all outputs have one input

Yes, because all inputs have one output

Yes, because all outputs have one input

No, because the lines are not straight across

Yes, because all inputs have one output

Yes, because all outputs have one input

Yes, because all inputs have one output

Yes, because all outputs have one input

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

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

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

No, because a vertical line touches only one point on the relation

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

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

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

No, because a vertical line touches only one point on the relation

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

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

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

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

Yes, because none of the y coordinate (outputs) repeat itself.

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

No, because the x-coordinates repeat itself

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

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

Yes, because none of the y coordinate (outputs) repeat itself.

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

No, because the y-coordinates repeat itself

For the function {(0,1), (1,-3), (2,-4), (-4,1)}, write the domain and range.

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

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

For the function {(0,1), (1,-3), (2,-4), (-4,1)}, write the domain and range.

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

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

Does the graph represent a function?

No, because the vertical line test shows there are repeating input values

Yes, because the vertical line test shows there are no repeating input values

Is the relation a function? Why.

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

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 each x-value has only one y-value paired with it.
