Answer 2

Functions need only one value of 'x'..so which one has more than one value of 'x'?

Answer 3

You got it?

Answer 4

Look at the 'x' values for each table, see which one has a repeat.

Answer 5

Well, function is a special case of relation, which generates a single output for every given input.
So basically, if the same x value could generate different y values then it is not a function of x.
It could still be a function of y, so you have to check it for y as well.

Answer 6

D?

Answer 7

No, the x-values in D are -8, -4, -2, and 1

None of these are the same, so it is a function
