For Questions 4-6, Graph The Solution Set Of The Inequality.4. $\sqrt{x} \ \textgreater \ -2$

$$

Introduction

Graphing the solution set of an inequality is a crucial concept in mathematics, particularly in algebra and geometry. It involves visualizing the set of all possible solutions to an inequality on a number line or a coordinate plane. In this article, we will focus on graphing the solution set of the inequality $\sqrt{x} \ \textgreater \ -2$. We will explore the steps involved in graphing the solution set, and provide a detailed explanation of the process.

Understanding the Inequality

The given inequality is $\sqrt{x} \ \textgreater \ -2$. This means that the square root of $x$ is greater than $-2$. To solve this inequality, we need to isolate the variable $x$.

Solving the Inequality

To solve the inequality, we can start by squaring both sides of the inequality. This will eliminate the square root sign and allow us to isolate the variable $x$.

$\sqrt{x} \ \textgreater \ -2$

Squaring both sides:

$x \ \textgreater \ (-2)^2$

$x \ \textgreater \ 4$

Graphing the Solution Set

Now that we have solved the inequality, we can graph the solution set on a number line. The solution set consists of all values of $x$ that satisfy the inequality $x \ \textgreater \ 4$.

To graph the solution set, we can use the following steps:

1. Draw a number line and mark the point $x = 4$.
2. Since the inequality is greater than $4$, we need to shade the region to the right of $x = 4$.
3. The solution set is all values of $x$ that are greater than $4$.

Visualizing the Solution Set

Here is a visual representation of the solution set:

Number Line:

$x$	$-$∞	$4$	$+$∞
Shaded Region

The shaded region represents the solution set of the inequality $\sqrt{x} \ \textgreater \ -2$. This region includes all values of $x$ that are greater than $4$.

Conclusion

Graphing the solution set of an inequality is an essential concept in mathematics. In this article, we have explored the steps involved in graphing the solution set of the inequality $\sqrt{x} \ \textgreater \ -2$. We have solved the inequality, isolated the variable $x$, and graphed the solution set on a number line. The solution set consists of all values of $x$ that are greater than $4$. This concept is crucial in understanding and solving inequalities, and it has numerous applications in mathematics and real-world problems.
