Introduction

In mathematics, an exponential function is a function that has the form $y = a^x$, where $a$ is a positive real number and $x$ is the variable. The table below represents an exponential function, where the values of $x$ and $y$ are given for different values of $x$. In this article, we will analyze the table and understand the pattern and interval between neighboring values.

The Table

$x$	0	1	2	3	4	5
$y$	1	4	16	?	256	1,024

Understanding the Pattern

From the table, we can see that the value of $y$ is increasing exponentially as the value of $x$ increases. The value of $y$ is obtained by raising a fixed number to the power of $x$. In this case, the fixed number is 2, since $2^0 = 1$, $2^1 = 4$, $2^2 = 16$, and so on.

Finding the Missing Value

To find the missing value of $y$ for $x = 3$, we can use the pattern we observed earlier. Since $y = 2^x$, we can substitute $x = 3$ into the equation to get $y = 2^3 = 8$. Therefore, the missing value of $y$ is 8.

The Interval Between Neighboring Values

The interval between neighboring values of $y$ is the difference between consecutive values of $y$. From the table, we can see that the interval between neighboring values of $y$ is increasing exponentially as the value of $x$ increases.

Calculating the Interval

To calculate the interval between neighboring values of $y$, we can use the formula:

Interval = $y_{n+1} - y_n$

where $y_n$ is the value of $y$ for $x = n$ and $y_{n+1}$ is the value of $y$ for $x = n+1$.

Using this formula, we can calculate the interval between neighboring values of $y$ as follows:

Interval = $4 - 1 = 3$ Interval = $16 - 4 = 12$ Interval = $256 - 16 = 240$ Interval = $1,024 - 256 = 768$

Analyzing the Pattern of the Interval

From the table, we can see that the interval between neighboring values of $y$ is increasing exponentially as the value of $x$ increases. The interval is obtained by multiplying the previous interval by a fixed number, which is 4 in this case.

Conclusion

In conclusion, the table represents an exponential function, where the values of $x$ and $y$ are given for different values of $x$. The pattern of the table is obtained by raising a fixed number to the power of $x$. The interval between neighboring values of $y$ is increasing exponentially as the value of $x$ increases. By analyzing the pattern of the table, we can understand the behavior of the exponential function and make predictions about the values of $y$ for different values of $x$.
