Is the function linear or exponential? Explain the reasoning.
The function is exponential because there is a constant rate of change: for every increase in z, the y-value increases by 1.3
The function is exponential because there is a proportional rate of change; for every increase in z, the y-value increases by a factor of 1.3.
The function is linear because there is a constant rate of change; for every increase in z, the y-value increases by 1.3.
The function is linear because there is a proportional rate of change: for every increase in z, the y-value increases by a factor of 1.3.

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.
