1. The problem statement, all variables and given/known data I am supposed to find out if this function is symmetric with reference to the y-axis or reference to the origin. The function is F(x)=4x^2/(x^3+x) 2. Relevant equations These are how to know if even or odd A(-x)^even power = ax^even power A(-x)^odd power = -ax^odd power 3. The attempt at a solution I think that to solve these u change x to -x in the function right? So I got... F(-x)=4-x^2/(-x^3-x) To F(-x)=4+x/(-x-x) To F(-x)=4+x/-2x To F(-x)=2+x/-x To -2 But now what, how do I tell if it's odd even or neither?? Did I even do the math right?
