What is the inverse of the logarithmic function
1 answer:
Answer:
<h2>C.Step-by-step explanation:
Given the logarithmic function f(x)= log₂x. To find the inverse of the function, we will follow the following steps.
Firstly, let y = f(x) so that y = log₂x
From the expression y = log₂x, we will make x the subject of the formula as shown;
If y = log₂x
Replacing y with x, the expression will become;
The function y above will be the inverse of the logarithmic function given.
Hence the inverse of log₂x is

Answer:
The residual value, which is the farthest from the line of best fit for the table which shows points and their residual values, is 0.7.
<h3>What is residual value?</h3>The residual value is the estimated value which is calculated for the end of the lease terms for a fixed asset.
Points and their residual values are shown in the table. A 3-column table with 5 rows.
- x 1, 2, 3, 4, 5.
- y 2, 3.5, 5, 6.1, 8.
- Residual Value -0.4, 0.7, -0.2, -0.6 0
The simple regression line can be represented as,
Here α is the constant, β is the slope and <em>e </em>is the residue.
The point which is farthest from the best fit of the line is 3.5. At y=3.5, the value of residue is 0.7.
Thus, the residual value, which is the farthest from the line of best fit for the table which shows points and their residual values, is 0.7.
