How do you evaluate the limit #-2w# as #w# approaches #2#?

Answer 1

#-4#

#lim_(w->2)(-2w)#

Plugging in 2 for w:

#-2(2)=-4#
#:.#
#lim_(w->2)(-2w)=-4#

Answer 2

-4

...your first step on this type of limit problem is to simply substitute the ending value of the variable into the expression, and see if it makes sense. (i.e., you don't end up dividing by zero).

In this case, just evaluate f(w) = -2w at w = 2. You get -4. So you can get on with your life.

GOOD LUCK.

Answer 3

To evaluate the limit of -2w as w approaches 2, we substitute the value of 2 for w in the expression -2w. This gives us -2(2) = -4. Therefore, the limit of -2w as w approaches 2 is -4.

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.
