The distance between two points is the number of units between them.
<u>Halfway points (a) and (b)</u>
To locate a point halfway points (a) and (b), we use the following steps
- Calculate the absolute difference between both points
- Divide the absolute difference by 2
- Add the quotient to the smaller point.
Assume the smaller value is (a), the point (P) halfway points (a) and (b) would be
Take for instance, a = 5, and b = 10.
The halfway point would be:
The halfway point between 5 and 10 is 7.5
The formula works for negative values, and absolute values are used to return the actual difference between both points
<u>Real world circumstance</u>
The formula can be used to calculate the halfway distance between a school gate and the school library (as an instance)
<u>Fractional distance</u>
To determine the fractional distance, we simply replace the 1/2 in the original formula with the appropriate fraction.
Take for instance, three-fourths from (a) to (b) would be:

The exponential function which has the greatest average rate of change over the interval [0, 2] is option B.
<h3>How to calculate the average rate of change?</h3>Mathematically, the average rate of change between two (2) points can be calculated by using this expression;
For option A, we have:
when x = 0; when x = 2;
y = 3(1.6)^x y = 3(1.6)^x
y = 3(1.6)^0 y = 3(1.6)^2
y = 3. y = 7.68
ΔA = (7.68 - 3)/(2 -0) = 2.34.
For option B, we have:
ΔA = (9 - 4)/(2 -0) = 2.5.
For option C, the exponential function has a common ratio of 2.
ΔA = 2.
For option D, we have:
ΔA = (10 - 8)/(1 -0) = 2.
In conclusion, we can logically deduce that the exponential function which has the greatest average rate of change over the interval [0, 2] is option B i.e 2.5.
