Math-way! Its a great website for math and explanations!!
Step-by-step explanation:
Given :
To Find :
the absolute minimum and absolute maximum values of f on the given interval
[-1,2] .
Solution :
Now , getting first order differential equation and equating its equal to zero.

So , x=0 is critical point .
Now , coefficient of
is positive .
Therefore , it is increasing function after x=0 .
So , min value will be at , x=0.

And maximum value will be the maximum at the x=2 because it is increasing function .

Therefore , max and min value is 9 and -3 respectively .
Hence , this is the required solution .
2x + x = 54 wher x = number of girls
3x = 54
x = 18
18 girls
6y + x = y --> Subtract y from both sides
5y + x = 0 --> Subtract x from both sides
5y = - x --> Divide both sides by 5
y = - x/5 (Notice that it's negative.)
