What is the domain of the given function?
{x|x = -6, -1, 0,3}
{yly = -7,-2, 1,9}
{x|x = -7, -6, -2,-1, 0, 1, 3,9}
{yly = -7, -6, -2,-1, 0, 1, 3, 9}

Look at the following graph of the given equation. determine whether the equation is a function. explain why or why not.

When y’all answer can y’all explain too !

Use the given degree of confidence and sample data to construct a confidence interval for the population mean mu . assume that the population has a normal distribution. a laboratory tested twelve chicken eggs and found that the mean amount of cholesterol was 185 milligrams with sequals 17.6 milligrams. a confidence interval of 173.8 mgless than muless than 196.2 mg is constructed for the true mean cholesterol content of all such eggs. it was assumed that the population has a normal distribution. what confidence level does this interval represent?
