Average rate of change is calculated using the slope of
*
25 points
a tangent line at one point
a tangent line between two points
a secant line at one point
a secant line between two points
Instantaneous rate of change of a function is based on:
*
25 points
the domain of the function
the derivative of the function
the range of the function
the inverse of the function
To find instantaneous rate of change on a GRAPH, it is necessary to:
*
25 points
find the area under the curve
calculate the slope between two known points on the graph
sketch a tangent line and approximate the slope of that line
find the lowest y-value on the graph
If we are given a table, how do we approximate the instantaneous rate of change at a given x-value?
*
25 points
Calculate the average rate of change between the two closest x-values on either side of the given x-value.
We can't approximate because the derivative is always undefined in a table.
Calculate the average rate of change between the two endpoints of the table.
Calculate the slope at every x-value in the table, and find the average.
