2. For the three-part question that follows, provide your answer to each part in the given workspace. Identify each part with a coordinating response. Be sure to clearly label
each part of your response as Part A, Part B, and Part C.
Part A: Explain what the roots of a function are and how to find them.
Part B: Calculate the zeros of the function y=-x^2- 4x + 21.
Part C: Describe the graph of the function from Part B, including key characteristics of
the function.

an advantage of the standard deviation is that it increases as the dispersion of the data increases. e. the interquartile range is preferred when the data are not skewed or no have outliers. an advantage of the standard deviation is that it uses all the observations in its computation.

the least value out of the data shown is 5, maybe if you post a picture with it i could a little more.

step-by-step explanation:

on monday rodney ate 1/4th of the sandwich = 3/12

on tuesday he ate 1/3rd of the sandwich = 4/12

therefore in total he has eaten = 3/12 + 4/12 = 7/12

thus we can say that he has eaten 7/12 of the sandwich on monday and tuesday alltogether.

happy to

pls mark as brainliest.
