$**Understanding the Function $f(x)=3(\sqrt{18})^x$**$

Analyzing the Function

The given function is $f(x)=3(\sqrt{18})^x$ . To understand the function, we need to break it down and analyze its components. The function consists of a constant term, $3$ , and an exponential term, $(\sqrt{18})^x$ . The exponential term is raised to the power of $x$ , which means that the function will grow or decay exponentially as $x$ increases or decreases.

Domain of the Function

The domain of a function is the set of all possible input values for which the function is defined. In this case, the function is defined for all real numbers, since there are no restrictions on the value of $x$ . Therefore, the domain of the function is all real numbers.

Range of the Function

The range of a function is the set of all possible output values. To determine the range of the function, we need to consider the behavior of the exponential term. Since the base of the exponential term is $\sqrt{18}$ , which is greater than $1$ , the function will grow exponentially as $x$ increases. Therefore, the range of the function is all real numbers greater than $3$ .

Initial Value of the Function

The initial value of a function is the value of the function when $x=0$ . To determine the initial value of the function, we need to substitute $x=0$ into the function. This gives us:

$f(0)=3(\sqrt{18})^0$

Since any number raised to the power of $0$ is equal to $1$ , we have:

$f(0)=3(1)=3$

Therefore, the initial value of the function is $3$ .

Selecting the Correct Options

Based on our analysis, we can select the correct options:

A. The domain is all real numbers. Correct
B. The range is $y \ \textgreater \ 3$ . Correct
C. The initial value is 3. Correct
D. The initial value is 9. Incorrect
E. The function is always increasing. Incorrect

Therefore, the three correct options are A, B, and C.

Conclusion

In conclusion, the function $f(x)=3(\sqrt{18})^x$ has a domain of all real numbers, a range of all real numbers greater than $3$ , and an initial value of $3$ . These results can be used to understand the behavior of the function and to make predictions about its output values.

Key Takeaways

The domain of the function is all real numbers.
The range of the function is all real numbers greater than $3$ .
The initial value of the function is $3$ .

Further Analysis

To further analyze the function, we can consider its behavior as $x$ increases or decreases. Since the base of the exponential term is greater than $1$ , the function will grow exponentially as $x$ increases. This means that the function will become larger and larger as $x$ increases.

On the other hand, since the base of the exponential term is greater than $1$ , the function will decay exponentially as $x$ decreases. This means that the function will become smaller and smaller as $x$ decreases.

Graphing the Function

To visualize the behavior of the function, we can graph it on a coordinate plane. The graph of the function will be a curve that grows exponentially as $x$ increases and decays exponentially as $x$ decreases.

Real-World Applications

The function $f(x)=3(\sqrt{18})^x$ has several real-world applications. For example, it can be used to model population growth or decay, where the population grows or decays exponentially over time.

It can also be used to model financial growth or decay, where the value of an investment grows or decays exponentially over time.

Conclusion

In conclusion, the function $f(x)=3(\sqrt{18})^x$ is a powerful tool for modeling exponential growth or decay. Its domain is all real numbers, its range is all real numbers greater than $3$ , and its initial value is $3$ . These results can be used to understand the behavior of the function and to make predictions about its output values.
