Question

Find the limit of the function by using direct substitution. lim(x^2-1) x->0

Answer 1

-1

Explanation:

Direct substitution is just filling in the limit for x then solving. So in this case the limit is 0.

x^2-1

0^2-1

-1

Answer 2

Find the following limit:
lim_(x->0) (x^2 - 1)
lim_(x->0) (x^2 - 1) = 0^2 - 1 = -1:
Answer: -1
