On average, a single apple tree produces 600 apples in a month; however, overcrowding can diminish a tree’s yield. For every tree over 30 trees in an acre of apple orchard, the number of apples produced by each tree goes down by 10 apples per month. (a) Construct a formula for the number of apples A(t) produced in a month if t trees are planted in an acre. (HINT: you might need a piecewise function) (b) Find the domain of A. (c) Find the maximum number of apples an acre of trees can produce, and find the number of trees needed to yield that many apples. (d) Sketch the graph of A(t).
Minimization
In mathematics, traditional optimization problems are typically expressed in terms of minimization. When we talk about minimizing or maximizing a function, we refer to the maximum and minimum possible values of that function. This can be expressed in terms of global or local range. The definition of minimization in the thesaurus is the process of reducing something to a small amount, value, or position. Minimization (noun) is an instance of belittling or disparagement.
Maxima and Minima
The extreme points of a function are the maximum and the minimum points of the function. A maximum is attained when the function takes the maximum value and a minimum is attained when the function takes the minimum value.
Derivatives
A derivative means a change. Geometrically it can be represented as a line with some steepness. Imagine climbing a mountain which is very steep and 500 meters high. Is it easier to climb? Definitely not! Suppose walking on the road for 500 meters. Which one would be easier? Walking on the road would be much easier than climbing a mountain.
Concavity
In calculus, concavity is a descriptor of mathematics that tells about the shape of the graph. It is the parameter that helps to estimate the maximum and minimum value of any of the functions and the concave nature using the graphical method. We use the first derivative test and second derivative test to understand the concave behavior of the function.
