Calculus and set of zeros help

In summary, Calculus is a branch of mathematics that deals with continuous change and is used to solve problems involving rates of change, optimization, and area/volume calculations. The two main types of Calculus are differential calculus, which deals with rates of change and slopes of curves, and integral calculus, which focuses on finding the area under a curve. A set of zeros, also known as a root or solution, is a value that makes the equation or function equal to zero and can be found using techniques such as factoring, the quadratic formula, or the rational roots test. Understanding sets of zeros is important because they help us solve real-world problems and play a crucial role in many areas of science and engineering.

Homework Statement



The set of zeros of f (x) = x^3 + 4x^2 + 4x is

A) {-2}
B) {0, -2}
C) {0, 2}
D) {2}
E) {2, -2}


2. The attempt at a solution

f (x) = x^3 + 4x^2 + 4x
f (x) = (x^2 + 2x)(x + 2)
f (x) = x(x + 2)(x + 2)

x = 0 and x = -2. Is the answer B?

What is Calculus?

Calculus is a branch of mathematics that deals with the study of continuous change. It is used to solve problems involving rates of change, optimization, and area/volume calculations.

What are the different types of Calculus?

The two main types of Calculus are differential calculus and integral calculus. Differential calculus is concerned with rates of change and slopes of curves, while integral calculus is focused on finding the area under a curve.

What is a set of zeros?

A set of zeros, also known as a root or solution, is a value that makes the equation or function equal to zero. In other words, it is the x-value where the graph of the function intersects the x-axis.

How is Calculus used to find sets of zeros?

Calculus can be used to find sets of zeros by setting the function equal to zero and solving for the variable using techniques such as factoring, the quadratic formula, or the rational roots test. Additionally, the Intermediate Value Theorem can be used to determine if a set of zeros exists within a given interval.

Why is understanding sets of zeros important?

Understanding sets of zeros is important because they can help us solve real-world problems, such as finding the maximum or minimum values of a function, determining the average rate of change, or finding the roots of a polynomial equation. They also play a crucial role in many areas of science and engineering, such as physics, economics, and statistics.
