To find the y intercept - set x=0

 

To find the x intercepts - set y = 0

Example:

->Solve for x

->opposite of squared is square root

-> +/- means that there are 2 possible x             intercepts

                                     

                                     2+1=x          -2+1 = x

                                     3=x              -1=x
