Click For Summary
The function f(x)=[e^(x^2)]/[x^2 -2] has no x-intercepts since setting y=0 yields no solutions. For critical points, the derivative must be calculated using the quotient rule, as the initial derivative provided was incorrect. The discussion indicates confusion regarding local maxima and minima due to the lack of critical points. Additionally, the existence of horizontal asymptotes needs to be evaluated based on the behavior of the function as x approaches infinity or negative infinity. Clarification on these key features is essential for a complete analysis of the function.

find all intercepts
find the critical points
does the function have a horizontal asymptote? justify answer
find local max and min points


Homework Equations





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.

What is the distance between the tips at the moment when it is increasing most rapidly?(Putnam Exam Question) Answer: Making assumption that both the hands moves at constant angular velocities, the answer is ## \sqrt{7} .## But don't you think this assumption is somewhat doubtful and wrong?
