On this problem, you may use a computer to calculate thederivative. Consider the function f(t) = (2t^2) / (3t^2 + 1) :
(a) On what intervals is the function concave up, and on whatinvervals is it concave down? Why? (b) (5 points) On what intervalsis the function increasing, and on what intervals is it decreasing?Why?
(b) On what intervals is the function increasing, and on whatintervals is it decreasing? Why?
