Given the function f(x)=[e^(x^2)]/[x^2 -2] , find all the key features

    1. The problem statement, all variables and given/known data
    Given the function f(x)=[e^(x^2)]/[x^2 -2]
    find all intercepts
    find the critical points
    does the function have a horizontal asymptote? justify answer
    find local max and min points


    2. Relevant equations



    3. The attempt at a solution
    to find x-intercepts, let y=0, therefore no x-intercepts?
    for critical points, find the derivative, which is f'(x)=2xe^(x^2)/2x and let it equal to zero, which shows no critical points..
    stuck on this question..

    Your f'(x) is incorrect. You need to use the quotient rule.
