Use the Graph to Determine the Function's Domain and Range $x = 1$

question 26

Multiple Choice

Use the graph to determine the function's domain and range. Write the domain and range in interval notation.
-

• A) domain: \(x = 1\) range: \(( - \infty , \infty )\)
• B) domain: \(x = 1\) range: \(y = - 5\)
• C) domain: \(( - \infty , \infty )\) range: \(\mathrm { y } = - 5\)
• D) domain: \(( - \infty , \infty )\) range: \(( - \infty , \infty )\)

Definitions:

Mean

The mean is the average of a data set, calculated by adding all the numbers together and then dividing by the count of those numbers.

Confidence Limits

Lower and upper boundaries of a confidence interval.

Confidence Interval

A range of values, derived from sample data, that is likely to contain the value of an unknown population parameter.

Standard Error

Standard error measures the dispersion of sample means around the population mean, providing an insight into the precision of a sample mean as an estimate of the population mean.
