# How to find the max and min of a polynomial function

Let a, b ∈ R and b ⩾ 0. Given that x 4 + a x 2 + b = 0 has 2 real solutions, find maximum for | a − b | and minimum for a + 2 b. My solution : x 4 + a x 2 + b = 0 ( x 2 − c) ( x 2 −

## How to Find a Maximum Value for a Polynomial

Now you can Identify the extrema which one is minima and which one is maxima .Then you may use this function to plot Minima marked as 'o' and Maxima marked as '*'. fplot

## How do you find the absolute maximum and minimum of the

Summary. A minimum or a maximum is called an extreme point. A local extreme point is the smallest or largest value in its neighborhood. If it is also the smallest or largest at the entire domain of the function, it is called a global

SOLVING

Solving problems is a skill that can be learned.
