24a-18a+12a is equal to 18a
hence, divide it by 6a
so you get 3a :)
Answer:
absolute max is 120 and absolute min is -8
Step-by-step explanation:
Find critical numbers
f'(x) = 3x^2 - 12x + 9 = 0
= 3(x^2 - 4x + 3) = 0
3(x-3)(x-1) = 0
(x-3) = 0 or (x-1)=0
x = 1,3
Test them!
x<1 Sign of f' on this interval is positive
1<x<3 Sign of f' on this interval is negative
x>3 Sign of f' on this interval is positive
f(x) changes from positive to negative at x = 1 which means there is a relative maximum here.
f(x) changes from negative to positive at x = 3 which means there is a relative minimum here.
Test the endpoints to find the absolute max and min.
f(-1) = -8
f(1) = 12
f(3) = 8
f(7) = 120
The absolute maximum value of f is 120 and the absolute minimum value of f is -8.

<h2> Hey, Option C is correct.....</h2>
Answer:
Step-by-step explanation:
The main difference between an ogive and a frequency polygon is - An ogive is a plot of cumulative values while a frequency polygon is a plot of the values themselves. An ogive is also called the cumulative frequency graph. It is a curve which shows the cumulative frequency of a given set of data.
