Answer 1

B, 2 and 3 only.

Explanation:

The first function can be eliminated because a sideways parabola is always NOT a function. This is because the x values are repeated, and in a function x-values are not repeated.

Function 2 is a function because no x-values are repeated, all x-values are different and not one x-value has multiple y-values.

Function 3 is a function because it's an equation in slope intercept form which always forms a line- meaning no x-values are repeated.

Function 4 is not a function because one of the x-values are repeated (2, 3) and (2, 5).
