Consider the tables that represent a continuous function and its inverse. Which is an accurate comparison of the functions? The reciprocal of the slope of f(x) is the same as the slope of f–1(x). The negative reciprocal of the slope of f(x) is the same as the slope of f–1(x). The y-coordinate of the y-intercept of f(x) is the same as the y-coordinate of the y-intercept of f–1(x). The opposite of the y-coordinate of the y-intercept of f(x) is the same as the x-coordinate of the x-intercept of f–1(x).

Jeffery conducted a survey in his school and found that 30 of the 50 eighth grade students' favorite subject is mathematics. based on the results, jeffery concluded that out of the 200 students in his school, 120 students' favorite subject is mathematics. select the statement that is true about jeffery's conclusion. a. jeffery's conclusion is not valid because the sample was biased since only 200 students were surveyed. b. jeffery's conclusion is valid because the sample was random since all of the students were eighth grade students. c. jeffery's conclusion is valid because the sample was random. d. jeffery's conclusion is not valid because the sample was biased since all of the students were eighth grade students.
