1. Explain why, without restrictions, no trigonometric function has an inverse function.
2. Sine
o Describe the restriction on the function so that it has an inverse.
o Without drawing a graph, describe the behavior of the inverse
graph. Mention the function's domain and range in your description.
3. Cosine
o Describe the restriction on the function so that it has an inverse.
• Without drawing a graph, describe the behavior of the inverse
graph. Mention the function's domain and range in your description.
4. Tangent
o Describe the restriction on the function so that it has an inverse.
o Without drawing a graph, describe the behavior of the inverse
graph. Mention the function's domain and range in your description.
5. Are the domains of the restricted trigonometric functions the same as the
intervals on which the nonrestricted functions complete one cycle?
Creating a table the shows the function, intervals and cycle may make it
easy to justify your answer.

Apoll is being conducted at a mall nothingto obtain a sample of the population of an entire country. what is the frame for this type of​ sampling? who would be excluded from the survey and how might this affect the results of the​ survey? what is the frame for this type of​ sampling? a. the frame is people who need new clothes. b. the frame is people who shop at the mall. c. the frame is people who like to shop. d. the frame is the entire population of the country. who would be excluded from the survey and how might this affect the results of the​ survey? a. any person that does not need new clothes is excluded. this could result in sampling bias due to undercoverage. b. any person who does not shop at the mall is excluded. this could result in sampling bias due to undercoverage. c. any person who does not shop at the mall is excluded. this could result in nonresponse bias due to people not participating in the poll. d. there is nobody that is being excluded from the survey.
