Does this mapping diagram represent a function?

Yes, because there are no repeating input values

No, because there are 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.

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}

Is this a function? Explain.

Yes; it passes the vertical line test.

Yes; it passes the horizontal line test.

No; there is a line connecting the dots.

I throw a ball 10 feet in the air. If the domain is the number of seconds, what is a possible range for the function?
