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
The Y-intercept would be the value of y when x is at 0, which is when the Y axis is intercepted. -3/7 is the starting position of the function when the the X = 0.
