## What are the limits of polynomials?

The limit of a polynomial function can be found by finding the sum of the limits of the individual terms. See Example and Example. The limit of a function that has been raised to a power equals the same power of the limit of the function.

### What is the limitation of quadratic equation?

Quadratic Formula The disadvantages are that the formula provides no insight and can become a rote technique.

**Can quadratic functions have a limit?**

We can see that if we directly apply limit to the denominator of the given function, then the result will be undefined and the limit does not exist. So first we shall factorize the quadratic expression.

**Why does the quadratic formula always work?**

To answer your question, yes, the formula always works for quadratic equations, because from the equation ax2+bx+c=0, one can derive the formula x=−b±√b2−4ac2a manually. Here is a video on Youtube showing such a derivation.

## What is the benefits of quadratic equation?

The quadratic formulas can inspire you to do other units in mathematics. It is easy for the students who understand the quadratic equations to have different subjects correct. The ability to handle one unit can inspire the person to want to know other units in mathematics.

### How do you find the maximum or minimum value of a quadratic polynomial?

Finding max/min: There are two ways to find the absolute maximum/minimum value for f(x) = ax2 + bx + c: Put the quadratic in standard form f(x) = a(x − h)2 + k, and the absolute maximum/minimum value is k and it occurs at x = h. If a > 0, then the parabola opens up, and it is a minimum functional value of f.

**What do you mean by limit?**

1a : something that bounds, restrains, or confines the age limit for junior golf. b : the utmost extent pushed her body to the limit. 2a : a geographic or political boundary. b limits plural : the place enclosed within a boundary : bounds into the limits of the North they came— John Milton.

**What are properties of limits?**

1) Sum Rule: The limit of the sum of two functions is the sum of their limits. 2) Difference Rule: The limit of the difference of two functions is the difference of their limits. 3) Product Rule: The limit of a product of two functions is the product of their limits.

## Who discovered quadratic equation?

Around 820AD, near Baghdad, Mohammad bin Musa Al-Khwarismi, a famous Islamic mathematician5 who knew Hindu mathematics, also derived the quadratic equation.

### What is a quadratic used for?

Quadratic equations are commonly used in situations where two things are multiplied together and they both depend on the same variable. For example, when working with area, if both dimensions are written in terms of the same variable, you use a quadratic equation.

**What is maximum and minimum value of quadratic equation?**

When we find the maximum value and the minimum value of ax^2 + bx + c then let us assume y = ax^2 + bx + c. Thus, the minimum value of the expression is 4ac – b^2/4a. Therefore, we clearly see that the expression y becomes maximum when a < 0. Thus, the maximum value of the expression is 4ac – b^2/4a.
