Answer :
Word Count : 375
To find the local minima and maxima of ( f(x) = 3 - 5x^3 + 5x^4 - x^5 ), we first calculate the derivative: [ f'(x) = \frac{d}{dx}\big(3 - 5x^3 + 5x^4 - x^5\big) = -15x^2 + 20x^3 - 5x^4 ] Factor out (-5x^2): [ f'(x) = -5x^2(3 - 4x + x^2) ] Set ( f'(x) = 0 ) to find critical points: [ -5x^2(3 - 4x + x^2) = 0 ] This gives: [ ____ __________ ___ ______ ____ ___ _________ _____.
