Find limit using direct substitution

Question

Find the limit of the function by using direct substitution.

Question options:

1)	Does not exist
2)	−6
3)	6
4)	0

Answer 1

To solve these types of problems, you simply substitute the value that x is going to, in this case "0".

So substitute 0 for x in the argument x^2-6 and get 0^2-6 which is -6 .
