## What was the inflation rate in 1987?

3.65%The inflation rate in 1987 was 3.65%. The 1987 inflation rate is higher compared to the average inflation rate of 2.55% per year between 1987 and 2021. Inflation rate is calculated by change in the consumer price index (CPI).

## Does average rate of change mean slope?

Average Rate of Change = Slope. ... The average rate of change is finding how much something changes over time. This is very much like finding the slope of a line. If you recall, the slope of a line is found by finding the change in y divided by the change in x.

## During which time period is the average rate of change zero?

A zero rate of change is achieved when f (b) = f (a) giving a numerator of zero. When the average rate of change is zero, the sum of all possible positive slopes and negative slopes on the interval will be zero.

## How is the average rate of change of a function related to slope?

## Is the average rate of change the derivative?

1 Answer. The average rate of change gives the slope of a secant line, but the instantaneous rate of change (the derivative) gives the slope of a tangent line. Also note that the average rate of change approximates the instantaneous rate of change over very short intervals.

## Is the average rate of change the same as the slope?

Since the average rate of change of a function is the slope of the associated line we have already done the work in the last problem. That is, the average rate of change of from 3 to 0 is 1.

## Is the instantaneous rate faster than the average rate?

The instantaneous rate of change is the change at that particular moment or the gradient at that point. ... The key difference between the two is that the average rate of change is over a range, while the instantaneous rate of change is applied at a particular point.
