Answer 1

Answer:

No, it is not a function.

Step-by-step explanation:

Answer 2

Answer:

• No

Step-by-step explanation:

Given equation:

• y^2-x^2=16

Convert this to:

• y = ± $\sqrt{x^2 + 16}$

As we see each x-coordinate has two y-values referenced, it doesn't pass the vertical line test, this is not a function.
