Find the average rate of change of f(x) = 4x² – 3 from 3 to 9. The average rate of change of f(x) = 4x2 - 3 from 3 to 9 is
(Simplify your answer.)

44

Step-by-step explanation:

Given:

Required:

Average range of change from 3 to 9

SOLUTION:

Step 1:

Find f(3) and f(9):

To find f(3), replace x with 3 in the given function

To find f(9), replace x with 9 in the given function

Average rate of change =

Where,

Plug in the values into the formula for average rate of change.

Average rate of change = 44

(d)

step-by-step explanation:

given: the line in the graph passes through points (5,30) and (6,26).

then, the equation of line is:

now, put y=a(n) and x=n,

hence, option d is correct.
