The height of a falling object can be modeled by the equation h=-16t“ + vt +h, where
V is the initial velocity in feet per second, t is time in seconds, and h, is the initial height
in feet. Is the function linear or nonlinear, and why?
a. It is linear, because the object falls in a straight line.
b. It is linear, because the object falls at a constant speed.
c. It is nonlinear, because the object does not fall in a straight line.
d. It is nonlinear, because the object does not fall at a constant speed.

What is the ratio of the change in y-values to the change in x-values for this function? a) 1: 13 b) 2: 5 c) 5: 2 d) 13: 1

The final cost of a sale is determined by multiplying the price on the tag by 75%. which best describes the function that represents the situation?

The table below represents the displacement of a fish from its reef as a function of time: time (hours) x displacement from reef (feet) y 0 4 1 64 2 124 3 184 4 244 part a: what is the y-intercept of the function, and what does this tell you about the fish? (4 points) part b: calculate the average rate of change of the function represented by the table between x = 1 to x = 3 hours, and tell what the average rate represents. (4 points) part c: what would be the domain of the function if the fish continued to swim at this rate until it traveled 724 feet from the reef? (2 points)
