this wont be graded but i need the help with it

Answer:
f(-1) = 0
f(0) = -1
f(1) = 0
Explanation:
Given the below function;
[tex]f(x)=x^2-1[/tex]We're to find the corresponding values of f(x) given different values of x.
To determine the value of f(x) for each value of x, all we need to do is to substitute the said value of x into the function and solve for f(x).
When x = -1, let's go ahead and find f(-1);
[tex]f(-1)=(-1)^2-1=1-1=0[/tex]When x = 0, let's solve for f(0);
[tex]f(0)=(0)^2-1=0-1=-1[/tex]When x = 1, let's solve for f(1);
[tex]f(1)=(1)^2-1=1-1=0[/tex]
