If Jenny's car uses less gas per mile driven than Sandra's truck how does the graph representing the rate of change of Sandra's truck compare to the graph representing the rate of change of Jenny's ca?
The answer depends on the rate of change of WHAT? The rate of change of the gas used? the rate of change of the gas left, the rate of change of the range that the vehicle will go? The question is too vague.
How do you determine if a rate of change is constant?
You can determine if a rate of change is constant, by taking the instantaneous rate of change at multiple points - if they are all equal to each other, it can be assumed that the rate of change is constant. Alternatively, you can differentiate the function (if there is an associated function) - if this comes to a constant i.e. a number, then the rate of change is constant.
What is a constent rate of change?
Constant rate of change is is counting by 10s or and even number
What is an example of a negative rate of change?
a car braking is a negative rate of velocity change
Does the rate of change have to be negative?
no... the sign indicates whether the rate of change is increasing or decreasing. It is only negative if the rate is decreasing over time.
