Question 1040587: I am stuck on this problem, please help me.
Graph the function y=x^2-1 for the domain of (-2,-1,0,1,2).
Please explain how you got the answer, thank you in advance !
Answer by Boreal(15235) (Show Source): You can put this solution on YOUR website!
y=x^2-1
when x is -2, (-2)^2=4, and 4-1=3, so y=3
when x is 2, (2^2)=4, and 4-1=3, so y=3
when x is (-1), (-1^2)=1, and 1-1=0
when x=1, y=0
when x=0, x^2-1= -1
graph is symmetrical around the y-axis. The y-intercept is where x=0, which is -1
