Explanation Given information: The provided function is: h ( x ) = 1 − x 2 , for − 4 ≤ x < 0 h ( x ) = 1 − x , for 0 < x ≤ 1 h ( x ) = x − 1 , for 1 ≤ x ≤ 2 . Formula used: Do the following steps to find the absolute extrema of the function over an interval: Step 1. Find the value of f ′ ( x ) . Step 2. Find the critical values. Step 3. If the interval is closed and there is more than one critical value then use maximum-minimum Principle 1. Step 4. If the interval is closed and there is exactly one critical value use either maximum-minimum Principle 1 or maximum-minimum Principle 2. Step 5. If the interval is not closed and the function has only one critical point then use Maximum-minimum Principle 2. In this case the function has either only maximum or only minimum. Calculation: Consider the provided function: h ( x ) = 1 − x 2 , for − 4 ≤ x < 0 h ( x ) = 1 − x , for 0 < x ≤ 1 h ( x ) = x − 1 , for 1 ≤ x ≤ 2 . Now, look at each piece of function for any critical values as: For − 4 < x < 0 : h ' ( x ) = − 2 x For 0 < x < 1 : h ' ( x ) = − 1 For 1 ≤ x ≤ 2 : h ' ( x ) = 1 Therefore, there are no critical values of h ( x ) in the provided intervals

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 ter…

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 …

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 …
