Find the limit of the function by using direct substitution. limit as x approaches zero of quantity x squared minus two.

Step-by-step explanation:

We have the following limit

To solve this limit using direct substitution to substitute the value that tends x into f(x) and simplify.

In this case x tends to zero, then we substitute x = 0 in the function and simplify

Therefore

When x approaches 0 then f(x) it tends to -2
