1. The problem statement, all variables and given/known data Consider the equation below. (Round the answers to two decimal places. If you need to use -infinity or infinity, enter -INFINITY or INFINITY.) f(x) = x^4 - 50x^2 + 4 Find the local minimum and maximum values of f. 2. Relevant equations First derivative test and that is about it 3. The attempt at a solution Take the derivative using the power rule so f ' (x)= 4x^3-100x Then to find critical points, set f' (x)=0 and solve for x 0=4x^3-100x 0=4x(x^2-25), x=-5,0,5 then plug those x values into the original function and you get f(0)=4 ------max f(-5)= -621-----min f(5)=-621------min This is what i get for an answer, however the where I can type these answers online there are only two boxes. One is for min and one is for max. What did i do wrong?
