Find the limit of the function by using direct substitution. limit as x approaches zero of quantity x squared minus one. −1 does not exist 1 0

The given function is:
x^2 - 1
We want to calculate the limit of this function as x approaches zero. To do so, we will use direct substitution.
We will substitute the x with 0 in the given function to calculate its limit as follows:
Limit as x approaches 0 = (x)^2 - 1 = -1

Therefore, the correct choice is:
 -1

There is no graph but what i can say is that 1 is the slope and that -2 is the y- intercept

Sorry i really need my points
