F⁻¹(x) stands for the invers of function f(x). The inverse of f(x) is equal to x. We need to solve for x.
solve for x
f(x) = 2x + 2
2x + 2 = f(x)
2x = f(x) - 2
x =
f⁻¹(x) =
Determine the value of f⁻¹(x) when x = 4
f⁻¹(x) =
f⁻¹(4) =
f⁻¹(4) =
f⁻¹(4) = 1
When x = 4, the value of f⁻¹(x) is equal to 1
I think 6 but I’m not sure also how I got this answer is by simplifying 3/2 to 1 and a half so than I did 7 and a half - 1 and a half
In the research, the distribution is described by its shape. If there are more higher values than lower values, the distribution is skewed left.
<h3>How to illustrate the research?</h3>
It should be noted that when the distribution of data is skewed to the <u>left</u>, the mean is less than the median.
The distribution can be described by its center. If the distribution is skewed left or right, the <u>median</u> is an accurate measure of center.
The distribution can be described by its spread. If the data set does not have an outlier, the interquartile range is an accurate measure of spread.

Answer: 16590
Step-by-step explanation:
The formula we use to find the sample size is given by :-
, where p = prior estimate of population proportion.
= Critical z-value (Two- tailed)
E= Margin of error .
Let p be the population proportion of cyanobacteria.
Given : E = 0.01
Critical value for 99% confidence interval : 
If Ian does not want to rely on previous knowledge , then we assume p=0.5 because the largest standard error is at p=0.5.
Now, the required sample size = 
Required sample size = 16590
I would say all real numbers as the domain for this would be (-∞,∞).
However, I may be wrong, math is not my strong suit.
