If a sample of 26 students is taken from a population of 135 students, the
population variance, 02, is the variance of how many students' heights?
O A. 26
B. Neither 26 nor 135
O C. Both 26 and 135
O D. 135

Polynomial that can be factored as (3x-4)(3x+4)

What is the range of the function? f(x)=-2|x+1|? a. all real numbers. b. all real numbers less than or equal to 0. c. all real numbers less than or equal to 1. d. all real numbers greater than or equal to 1

For the functions f(x) = -922 – 2x and g(x) = -32? + 6x – 9, find (f - g)(x) and (f - ).
