Given

To obtain the minimum value of y, we first take the derivative of y
The derivative of y is:

Equating

gives the minimum value we require.
Doing that, we have:

So that

Therefore, the minimum value is x = 3
-4/7 > -2
If it is greater it goes to the right, and if it is less it goes to the left.
-4/6 is located to the right of -2
Answer:
As shown in picture, this is an isosceles right triangle ( A = 90 deg, B = C = 45 deg). => Except hypotenuse, side1 = side2, or x =

100+4x =7x
100=3x
100/3 = 33.33
x = 33.33 round up to 34
