The Table of Exponential Function: Understanding the Vertically Shifted Parent Function

In mathematics, exponential functions are a fundamental concept that plays a crucial role in various mathematical operations and applications. The parent function, ${$ f(x) = 2^x $}$, is a basic exponential function that serves as a building block for more complex functions. When this parent function is vertically shifted, it results in a new function, ${$ g(x) $}$, which is represented in the table below.

x	0	1	2	3	4
g(x)	-11	-10	-9	-8	-7

The table represents the vertically shifted parent function, ${$ g(x) $}$, which has been transformed from the original parent function, ${$ f(x) = 2^x $}$. To understand the transformation, let's analyze the values in the table.

Analyzing the Values in the Table

x	g(x)
0	-11
1	-10
2	-9
3	-8
4	-7

From the table, we can observe that the values of ${$ g(x) $}$ are decreasing as the value of ${$ x $}$ increases. This indicates that the function is decreasing exponentially. To understand the relationship between the parent function and the vertically shifted function, let's compare the values of ${$ f(x) $}$ and ${$ g(x) $}$.

x	f(x)	g(x)
0	1	-11
1	2	-10
2	4	-9
3	8	-8
4	16	-7

From the table, we can observe that the values of ${$ f(x) $}$ are increasing exponentially, while the values of ${$ g(x) $}$ are decreasing exponentially. This indicates that the vertically shifted function, ${$ g(x) $}$, is a reflection of the parent function, ${$ f(x) $}$, about the x-axis.

To determine the vertical shift, let's analyze the difference between the values of ${$ f(x) $}$ and ${$ g(x) $}$.

x	f(x)	g(x)	Difference
0	1	-11	-12
1	2	-10	-12
2	4	-9	-13
3	8	-8	-16
4	16	-7	-23

From the table, we can observe that the difference between the values of ${$ f(x) $}$ and ${$ g(x) $}$ is constant, which is -12. This indicates that the vertically shifted function, ${$ g(x) $}$, has been shifted down by 12 units.

In conclusion, the table represents the vertically shifted parent function, ${$ g(x) $}$, which has been transformed from the original parent function, ${$ f(x) = 2^x $}$. By analyzing the values in the table, we can understand the relationship between the parent function and the vertically shifted function. The vertically shifted function, ${$ g(x) $}$, is a reflection of the parent function, ${$ f(x) $}$, about the x-axis, and has been shifted down by 12 units.
