Given the function defined in the table below, find the average rate of change, in simplest form, of the function over the interval 1 < x < 7.
x f（x）
1 95
3 61
5 35
7 17

step-by-step explanation:

a

step-by-step explanation:

answer: 33 ( approx)

step-by-step explanation:

since, in the linear regression formula, the slope is the a in the equation y = b + ax ( by comparing it with the general equation of line y = mx + c )

where,

here given table is,

price ($), x   :           18         23       25       29       30       33

pairs sold, y :         16         13         10       8         6       2

so, ,   ,   ,

and   ,

thus, slop of the given line is,

⇒  

⇒   ≈ 33
