Find the average rate of change of f(x) = 4x² – 3 from 3 to 9.
Lina20 [59]

Answer:

44

Step-by-step explanation:

Given:

f(x) = 4x^2 - 3

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

f(3) = 4(3)^2 - 3

f(3) = 4(9) - 3

f(3) = 36 - 3

f(3) = 33

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

f(9) = 4(9)^2 - 3

f(9) = 4(81) - 3

f(9) = 324 - 3

f(9) = 321

Average rate of change = \frac{f(b) - f(a)}{b - a}

Where,

a = 3, f(a) = 33

b = 9, f(b) = 321

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

= \frac{321 - 33}{9 - 3}

= \frac{288}{6}

= 44

Average rate of change = 44

when 3 is subtracted from one third of a number n the result is less than 6. which inequality and solution represents this situa
katen-ka-za [31]

Answer:

1/3n-3<6

Step-by-step explanation:

One third of a number: 1/3

3 is subtracted from 1/3 of a number n: 1/3n -3

Result is less than 6: less is represented with the symbol <. So, the result of the expression 1/3n-3 is less (<) than 6.

The final expression:

1/3n-3<6

Feel free to ask for more if needed or if you did not understand something.
