Answer 1

Answer:

1. Yes

2. No

3. Yes

4. Yes

Step-by-step explanation:

#1

Yes, this is a function.

None of the x-values have more than one possible value for y. None of the x-values are repeated in this table.

#2

No, this is not a function.

For each and every value of x, there can only be one y. The x-value 13 has two possible values of y, 4 and -4. This is represented in the coordinates (13, 4) and (13, -4).

#3

Yes, this is a function.

The graph passes the vertical line test. If you were the pass a vertical line through the graph, it would only be touching the graph once, wherever the vertical line is placed.

#4

Yes, this is a function.

The equation given is a quadratic equation for an original parabola. All parabolas, when not inverse, are functions. This parabola opens down, so it will pass the vertical line test.
