How do you find the limit of #x^3# as #x->-2#?

Answer 1

#-8#

The function #x^3# is defined for #x=-2#, so the limit will just be equal to the actual value of the function at #x=-2#.

#lim_(xrarr-2)x^3=(-2)^3=-8#

To find the limit of x^3 as x approaches -2, we can substitute -2 into the function. Thus, the limit is (-2)^3, which equals -8.

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.
