I think it’s positive correlation
I can't see them all the way
Answer: B) increasing for x < -4/3 and x > 4/3
decreasing for -4/3 < x < 4/3
<u>Step-by-step explanation:</u>
Graph the equation and follow the curve from left to right. If you are going up, it is increasing. If you are going down, it is decreasing.
Refer to the image below. Red is increasing. Blue is decreasing.
The vertices are at: x = -4/3 and x = 4/3
The approximate volume of each slice will be 63.5 inch². The total cake is divided into the four cylindrical slice.
<h3>What is volume?</h3>
It is defined as a three-dimensional space enclosed by an object or thing.
The volume of the slice is;

If the grandma cut four pieces, is the approximate volume of each slice that Hattie's grandma cut will be;
The approximate volume of each slice will be;

Hence, the approximate volume of each slice will be 63.5 inch².

which means either

or

. The equation has no solution, since

is always bounded between -1 and 1. The second has one solution at

, and any number of complete revolutions will also satisfy this equation, so in general the solution would be

where

is any integer.
So you could choose

and

.
