Given

1= x^2 - 6x

Required

The perfect number

The coefficient c of x in the above equation is:

c = -6

Divide by 2

c/2 = -3

Square both sides

(c/2)^2 = 9

Hence, the constant to add is:

On what intervals is the graph of f(x)=x^3-2x^2+5x+1 increasing?
amid [387]
f(x)=x^3-2x^2+5x+1\\ f'(x)=3x^2-4x+5\\
3x^2-4x+5=0\\\Delta=(-4)^2-4\cdot3\cdot5=16-60=-44
\Delta0 \Rightarrow the graph of the parabola is above the x-axis, so the derivative is always positive and therefore the initial function is increasing in its whole domain.

f(x)=0.5x^2-6\\
f'(x)=x
The function is decreasing when its first derivative is negative. The first derivative of this function is negative for x so for x\in(-\infty,0) the function is decreasing.

f(x)=\dfrac{x+1}{x-1}\qquad(x\not=1)\\
f'(x)=\dfrac{x-1-(x+1)}{(x-1)^2}=-\dfrac{2}{(x-1)^2}
The function is increasing when its first derivative is positive. The first derivative of this function is always negative therefore this function is never increasing.
