Given f '(x) = (2 - x)(6 - x), determine the intervals on which f(x) is increasing or decreasing. (2 points)

weeeeeb [17]

Answer:

Decreasing (2, 6); increasing on (-∞, 2) U (6, ∞)

Step-by-step explanation:

To determine where $f(x)$ is increasing or decreasing, we set $f'(x)=0$ and check for the intervals.

We see that $f'(x)=0$ when either $x=2$ or $x=6$ . Therefore, we'll need to check the intervals $(-\infty,2)$ , $(2,6)$ , and $(6,\infty)$

For the interval $(\infty,2)$ , we can pick $x=0$ . This means that $f'(0)=(2-0)(6-0)=(2)(6)=12>0$ , showing that $f(x)$ increases on the interval $(-\infty,2)$

For the interval $(2,6)$ , we can pick $x=4$ . This means that $f'(4)=(2-4)(6-4)=(-2)(2)=-4$ , showing that $f(x)$ decreases on the interval $(2,6)$

For the interval $(6,\infty)$ , we can pick $x=7$ . This means that $f'(7)=(2-7)(6-7)=(-5)(-1)=5>0$ , showing that $f(x)$ increases on the interval $(6,\infty)$

Therefore, $f(x)$ is increasing on $(-\infty,2)\cup(6,\infty)$ and is decreasing on $(2,6)$ .

Daniel made a bench that has a seat with an area of 16 square feet. The length and the width of the seat are whole numbers. The

agasfer [191]

Answer:

dimensions of the seat are 2 feet and 8 feet

Step-by-step explanation:

given data

area = 16 square feet

length = 4 times greater than the width

solution

we know that area is express as

Area = L × W .................1

here L is length and W is width

put here value we get

16 = L × W ...............2

and we know

L = 4W ( as given ) ...............3

so put that in equation 2 we get

16 = 4W × W

4W² 16

solve it we get

W = 2

so here put this value in equation 3 we get

L = 4 × 2

L = 8

so the dimensions of the seat are 2 feet and 8 feet
