Find the increasing and decreasing intervals. Also sketch the graph.Let f(x)=x4-128x2+10.Calculate the derivativef'(x)=Calculate the second derivativef''(x)=Note intervals are entered in the format (-00,5)U(7,00)(these are two infinite intervals). Enter "DNE" if theinterval is empty.On what interval(s)isf increasing?Increasing:On what interval(s)isf decreasing?Decreasing:On what interval(s)isf concave downward?Concave Down:On what interval(s)isf concave upward?Concave Up:What is the limitasx approaches infinity?Limit is:What is the limitasx approaches negative infinity?Limit is:Sketch the graph and submit with your work.
