So now we are dealing with the y intercept, meaning y = 0
When dealing with functions and graphs, functions are equal to y
For example, if we have the variable x and the function of x is called f(x) [said "f of x" in words], then when we graph it, x is x value as usual and the function of x is the y value
A function is just a set of rules that gives a result that changes with the variable it is based on
Side note, the letters used for functions don't matter at all, and in this case they use w and c(w)
So just find the spot that c(w) = 0 and then say what it represents
If w is the weeks since the shipping contract is signed, then over time we can expect the crates to leave/ be shipped off,
So if c(w) represents the crates left BASED on the weeks since the sign-off, then when c(w) = 0, that means there are no crates left
In this case, c(w) = 0 when w = 12
In English, all of the crates have been shipped after 12 weeks.
