Answer 2

Yes, the equation ( y = 12x ) represents a direct variation. To find the constant of variation (k), you can use the formula:

[ k = \frac{y}{x} ]

In this case, since ( y = 12x ), you can substitute any value of ( x ) and the corresponding value of ( y ) into the formula to find ( k ). For example, if ( x = 1 ), then ( y = 12(1) = 12 ). So, ( k = \frac{12}{1} = 12 ). Therefore, the constant of variation is 12.

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.
