Plz need answer now will mark which situations represent linear functions? check all that apply. a)the temperature rises and falls over the course of a day. temperature is a function of time. b)a baseball is hit into the outfield. the height of the ball is a function of time. c)a car goes 55 mph on the highway. distance is a function of time. d)a child grew 2 inches this year and 1 inch last year. height is a function of time. e)a movie director makes 2 movies per year. the number of movies is a function of the years.

Option C and E

Step-by-step explanation:

A linear function is represented by a straight line when graphed.

Linear function means a straight line with uniform rate of change.

A.   The temperature rises and falls means rate of change is not uniform.  So the function representing temperature as a function of time is not a linear function.

B.    A base ball was hit into outfield which achieved maximum height but goes down. So rate of change in height is not uniform so function representing height as a function of time is not linear.

C.    Car goes 55 mph on the highway so change in distance with respect to time will be a linear function.

D.    A child grew 2 inches this year and 1 inch last year so rate of change in height will not be a linear function.

E.    Movie director makes 2 movies per year. The number of movies represented by a function in terms of years will be linear showing a straight line.

Option C and E are correct.
