it is given by.
so, we can find the dot product by multiplying the corresponding values in each vector and adding them together
Step 1
get the dot product
let
then
therefore, the answer is

Step-by-step explanation:
The average rate of change of a function f(x) over an interval [a, b] is:
(f(b) − f(a)) / (b − a)
(f(4) − f(0)) / (4 − 0)
(7/17 − -1/5) / 4
(52/85) / 4
13/85
