There are few features that you can use to sketch any polynomial function

First is to find x-intercepts of that polynomial. x-intercepts are positions x axis at which function f(x) is equal to 0

Second feature is to find first derivative of the function f(x), make it equal to 0 and again find x values that make first derivative equal to 0. after that implement those x values in f(x) to find f(x) for those values. Now you have sets of (x,y)  which are local minimum and maximums of polynomail. Knowing these and with a bit of calculation you can  make a decent skecth of any polynomial.

You can also set x=0 to find y- intercept.

A pitcher of punch holds 2 gallons if 9 people share the entire pitcher how much do that get a peice
kirza4 [7]
To find how much each person will get, you have to divide the amount available by the people. There are 2 ways I believe we can do this.
First way
Let's divide.
2÷9= 2/9

Each person would get 2/9 of a gallon if they shared it.

≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡
Second way
I believe it would be easier to convert this into cups. There are 16 cups per gallon.
16×2= 32
Let's divide that by 9.
32÷9= 3 5/9 cups per person.
≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡
Each person would receive 2/9 of a gallon.

What makes b in the equation true 3/8 X 8/b
Gala2k [10]

\frac{3}{8} *  \frac{8}{b} =  \frac{3}{1} *  \frac{1}{b}  (I crossed simplify)

Next cross multiply;

3b = 1

b = 1/3

To check if the statement is true just substitute the value of b in the equation;

3b = 1

3(1/3) = 1

1 = 1
