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.

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 this a function? Explain.

Yes; it passes the vertical line test.

No; there is a line connecting the dots.

Which relation is NOT a function?

{(1,-5), (-1,6), (1,5), (6,-3)}

{(1,-5), (3,1), (-5,4), (4,-2)}

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}

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