Answer:
<em>The average rate of change is $25.5 per hour, option B.</em>
Step-by-step explanation:
<u>Average Rate of Change </u>
When we are explicitly given some function C(x), we sometimes need to know the rate of change of C when x goes from to
. It can be computed as the slope of a line
.
The provided function is
We are required to compute the average rate of change between the points
Let's compute
The average rate of change is $25.5 per hour, option B.
We can use the vertex form
to find the equation of the graph. We know that a is the coefficient, and since the graph opens upwards and is slightly stretched vertically, we know that a is 1/3. On the graph, we see that the vertex of the parabola is at (0,-1). Therefore, h is 0 and k is -1.
Our vertex form equation is
