Finding the Exponential Function
To determine the exponential function that fits the given data points, we can start by analyzing the values of f(x)
and x
provided in the table:
- x = 3, f(x) = 64
- x = 4, f(x) = 256
- x = 5, f(x) = 1024
From this data, we observe that:
64 = 4^3
256 = 4^4
1024 = 4^5
This indicates that each value of f(x)
can be expressed as a power of 4.
To derive the general form of the exponential function, we can express f(x)
as:
f(x) = 4^x
Next, we can confirm this function by checking if it produces the correct outputs for the given inputs:
- For x = 3:
f(3) = 4^3 = 64
- For x = 4:
f(4) = 4^4 = 256
- For x = 5:
f(5) = 4^5 = 1024
Since the outputs match the values in your table, we can conclude that the exponential function representing your data is:
Final Function
f(x) = 4^x
This function accurately represents the relationship between x
and f(x)
as observed in the table provided.
