How to know when a function has a max value.

Mathematics
1 answer:
tatiyna3 years ago
7 0
If you have the graph, or can draw the graph, the maximum is just the y value at the vertex of the graph. If you are unable to draw a graph, there are formulas you can use to find the maximum. If you are given the formula y = ax2 + bx + c, then you can find the maximum value using the formula max = c - (b2 / 4a).

Which of the following represents the set of possible rational roots for the polynomial shown below?
andriy [413]
You need to work out the variables of 20 (the last number) first: 
1, 2, 4, 5, 10, 20 
Lets call these folks "p" 
At that point you need to work out the components of the main coefficient (the number before the most astounding force of x): 
1 
Lets call this person "q" 
At that point you need to make all the conceivable divisions you can with: 
±p/q 
Since q is only 1, we are fortunate, so the conceivable normal roots are: 
±1/1,±2/1,±4/1,±5/1.±10/1,±20/1
