    use the product rule :) y' = u'v + uv' where : - u = x^4 - u' = 4x^3 - v = e^x - v' = e^x just plug them in ^_^

    you'll have to factor first to find the zeros, lol it's alright, when you factor and get the zeros, your zeros will be the critical numbers and to find the points , you'll have to plug them in the original function to get the y's :)
