averaging the temperatures measured by five students whose names were picked from a stack of shuffled cards

B.
averaging the temperatures measured by five students who work together as a lab team

C.
averaging the temperatures measured by the six students with the highest scores on the last test

D.
averaging the temperatures measured by the first six students who enter the classroom the day after the experiment

The equation shown below represents function f. f(x)= -2x+5 the graph shown below represents function g. which of the following statements is true? a. over the interval [2, 4], the average rate of change of f is the same as the average rate of change of g. the y-intercept of function f is less than the y-intercept of function g. b. over the interval [2, 4], the average rate of change of f is greater than the average rate of change of g. the y-intercept of function f is greater than the y-intercept of function g. c. over the interval [2, 4], the average rate of change of f is the same as the average rate of change of g. the y-intercept of function f is greater than the y-intercept of function g. d. over the interval [2, 4], the average rate of change of f is less than the average rate of change of g. the y-intercept of function f is the same as the y-intercept of function g.
