Which of the following functions would be appropriate to use only positive integers

145

the function c (x) represents the cost for (X) people to attend the movies

the function p(w) represents the profit of a farmer who sells (W) whole watermelons the function h (p) represents the number of a person hours it takes to assemble (P) Engines in a factory

The answers are the function see parentheses x represents the cost for ( x) people to attend the movies.

The function P(W) represents the profit of a farmer who sells (w) whole watermelons.

The function 8 (p) represents the number of person hours it takes to assemble (p) in a factory

As the GCF is 3x let us write a polynomial and then multiply it by 3x.

Here is a polynomial: 

If we multiply it by 3x we get . Since we have a product (two expressions being multiplied together) this is factored. So this is the factored form of the polynomial we created with GCF of 3x.

Let’s multiply the terms in the parenthesis by 3x to get the same polynomial but written a different way:
. This is the factorable polynomial and the one we had before is the factored polynomial (also an equivalent form)

To get another equivalent form I could multiply out only the first term. This gives us  another equivalent form.
