My birthday is November 28, 2001. Therefore, it would be "11282001". Using the digits in order, my polynomial will be: f(x) = x^7+x^6+2x^5+8x^4+2x^3-3

PLEASE HELP ME WITH THIS FOLLOWING QUESTIONS! Will give brainliest!!

a. Zeros (x-intercepts) need a minimum of three:

b. y-intercept:

c. Relative (local) minimums and maximums:

d. What does your end behavior resemble (x^2, -x^2, x^3, or -x^3)

e. The number of turning points in the graph:

f. State the intervals of increasing and decreasing:

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?
