Need to find local and absolute maxima and minima for the equation: f(x)=(x-2)/(x^2-1) on the interval 0

PLEASE FIND THE DERIVATIVE

A large tank has a capacity of 300 gallons. Initially, the tank contains a brine solution of 200 gallons with 40 pounds of dissolved salt. A solution with a concentration of 4 pounds of salt per gallon is admitted into the tank and the well-stirred solution is withdrawn from the tank at a rate of 2 gallons per minute. a) Find the function (1) where y(1) represents the number of pounds of salt in the tank at f minutes. Give exact values here. b) Find the number of pounds of salt in the tank when the tank is completely full. Express your answer as a decimal with 1 decimal place accuracy.

Find the relative maxima and minima, if any, of h(t)=3-t^2/3 without using a graph.

For the function given, find all x-values where f' (x) > 0. f (x) = x^3 - 75x -8
