The graph has domain x ∈ ( 0 , +∞ )
It is first increasing and then decreasing. It has a local minimum and a global maximum.
- x^4 + x³ + 7 x² - x - 6 = ( x - 1 ) ( x + 1 ) ( x + 2 ) ( 3 - x )
The company will break even when P ( x ) = 0
The zeroes are: x 1 = 1, x 2 = 3
The company has a profit when: x ∈ ( 1, 3 )
" -20 + 5p - 7z " is not a question, and it doesn't beg for an answer.
It's an expression that stands for a number.
In order to determine what the number is, you need to know the
values of 'p' and 'z'. And if either of those changes, then the value
of " -20 + 5p - 7z " immediately changes too. So the whole thing is
a 'moving target'.
The answer to the problem is 36.
I dont remember that one sorry
