What is the Domain of the Function y=x+4y=\sqrt{x}+4?

The domain of a function is the set of all possible input values for which the function is defined. In other words, it is the set of all possible values of the variable x that can be plugged into the function without causing any problems or undefined results. In this article, we will explore the domain of the function y=x+4y=\sqrt{x}+4.

Understanding the Square Root Function

The square root function, denoted by x\sqrt{x}, is a mathematical function that returns the square root of a number. The square root of a number is a value that, when multiplied by itself, gives the original number. For example, the square root of 16 is 4, because 4 multiplied by 4 equals 16.

However, the square root function is only defined for non-negative numbers. This means that the square root of a negative number is undefined, because there is no real number that can be multiplied by itself to give a negative number.

The Domain of the Square Root Function

Since the square root function is only defined for non-negative numbers, the domain of the square root function is all non-negative real numbers. This can be represented mathematically as:

xβ‰₯0x \geq 0

Adding 4 to the Square Root Function

Now, let's consider the function y=x+4y=\sqrt{x}+4. This function is simply the square root function with 4 added to it. Since the square root function is only defined for non-negative numbers, the domain of the function y=x+4y=\sqrt{x}+4 must also be non-negative.

However, the addition of 4 to the square root function does not change the fact that the function is only defined for non-negative numbers. This means that the domain of the function y=x+4y=\sqrt{x}+4 is still all non-negative real numbers.

Finding the Domain of the Function

To find the domain of the function y=x+4y=\sqrt{x}+4, we need to consider the values of x that make the function defined. Since the function is only defined for non-negative numbers, we can set up the following inequality:

xβ‰₯0x \geq 0

This inequality represents all non-negative real numbers, which is the domain of the function y=x+4y=\sqrt{x}+4.

Comparing the Options

Now, let's compare the options given in the problem:

A. {-\infty \ \textless \ x \ \textless \ \infty$}$ B. {-4 \leq x \ \textless \ \infty$}$ C. ${0 \leq x \ \textless \ \infty\$} D. ${4 \leq x \ \textless \ \infty\$}

Only option C represents the domain of the function y=x+4y=\sqrt{x}+4, which is all non-negative real numbers.

Conclusion

In conclusion, the domain of the function y=x+4y=\sqrt{x}+4 is all non-negative real numbers. This can be represented mathematically as:

xβ‰₯0x \geq 0

The correct answer is option C, ${0 \leq x \ \textless \ \infty\$}.

Final Answer

The final answer is C.
