Hmmmm I’ll have to calculate this

We effectively rewrite the equation as

In order for the LHS to be defined, we need to restrict
, or
. Now, the LHS will vanish when the numerator is 0, which happens for

This value is indeed smaller than 4, so the solution is
.

15 hours will get 14×15 = 210loaves
Answer:
Hence , (a,0) is a zeros of a function
