How do you know if y=3x+2 is a function?
To determine if ( y = 3x + 2 ) is a function, we need to ensure that each input (value of ( x )) corresponds to exactly one output (value of ( y )). We can use the vertical line test: if a vertical line intersects the graph of the equation at more than one point, then the equation does not represent a function. In the case of ( y = 3x + 2 ), since every ( x ) value produces a unique ( y ) value, the equation represents a function.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
