∙ 15y agoy= cube root (x2-1) has domain infinity to negative infinity because the cube root of a negative number is still a real number. Look at cube root -8=-2 since (-2)(-2)(-2)=(-8) and (-1)(-1)(-1)=-1 so cube root of -1 =-1. So for any x, we can find a real number that satisfies cube root x^2-1
