a)Find the local extrema and identify them as either a local maximum or a local minimum. b)Find the coordinates of the absolute maximum and absolute minimum of the function in the interval

3
First, differentiate. Set f(x) to 0 Solve for x Factor Hence, we have local extrema at x = 10 and x = 20

4
To identify them as either maxima or minima, we can use the derivative -

2.A rectangular pen is to be fenced in using two types of fencing. Two opposite sides will use heavy duty fencing at $3/ft while the remaining two sides will use standard fencing at $1/ft. What are the dimensions of the rectangular plot of greatest area that can be fenced in at a total cost of $3600? 3x 1y Therefore max The dimensions of a rectangular plot of greatest area are 300 x 900
