Question 1

Why do you think that not all relations are not functions?

Accepted Answer

The value of x coordinate should not be repeated.

Answer

The value of y coordinate should not be repeated.

Answer

The value of z coordinate should not be repeated.

Answer

None of the above.

Question 2

Why do you think that the value of x coordinate is important to the y coordinate?

Accepted Answer

Because the x coordinate is independent variable, which means, the value of y coordinate relies on the value of the x coordinate.

Answer

Because the x coordinate is dependent variable, which means, the value of y coordinate does not rely on the value of the x coordinate.

Answer

Because both of them can be represented by any value as long as it is a real number.

Answer

None of the choices.
