Find the average velocity of the function over the given interval. y = 3/x - 2 (4,7)
a. -3/50.
b. 7.
c. 2.
d. 1/3.

Average velocity of the function over the given interval

              =  

Step-by-step explanation:

Explanation:-

Given function y = 3/x -2 ...(i)

The average velocity of the function over the given interval

             Average velocity  =

                               =    

now integrating

                           =  

                           =

                        =  

by using formulas

                 log a-log b = log(a/b)

  on simplification , we get                  

                 =

                =

Average velocity of the function over the given interval

              =  

step-by-step explanation:

total income = price of one ticket   *   number of tickets sold

  y                 =     4                                   x

so the equation is y=4x     with x≥0   because number of tickets sold can not be negative

thus the equation is a semi -line with an end point at

(0,0)

passing through :

x=1     y=4(1) = 4   so through (1,4)

3.07*10^-4

move the decimal 4 places to the left
