Please use "^" to denote exponentiation: f(x) = x^2 - 6x.
To find f(-a), replace "x" with "(-a)" in the function (x) = x^2 - 6x:
f(-a) = (-a)^2 - 6(-a) = a^2 + 6a (answer)

Step-by-step explanation:
Answer:
(B) A selected group of participants that is representative of a larger population
Step-by-step explanation:
A sample statistic is a piece of information that you get from a fraction of the population. This information is representative of a larger population.
For example, someone wants to conduct a survey about the most popular NFL team in Syracuse, NY, if it is the Buffalo Bills or the New York Giants. This person is not going to ask each person for whom they cheer. They are going to collect data from a fraction of the population and this data will be expanded to include the entire population.
So, the correct answer is:
(B) A selected group of participants that is representative of a larger population
A is the answer because its right according to the chart
1 whole thing = 6 sixths
3 whole things = 18 sixths
1 third of a whole thing = 2 sixths of it
3 wholes plus 1 third = 18 sixths plus 2 sixths = 20 sixths
