F(x)=x^3-7x-6  Since I don't have the graph and this is not a perfect cube, I will have to rely on Newton :P

x-(f(x)/(dy/dx))

x-(x^3-7x-6)/(3x^2-7)

(2x^3+6)/(3x^2-7), letting x1=0

0, -6/7, -.988, -.9999, -.99999999999, -1

(x^3-7x-6)/(x+1)

x^2 r -x^2-7x-6
-x   r  -6x-6
-6   r  0

(x+1)(x^2-x-6)=0

(x+1)(x-3)(x+2)=0

x= -2, -1, 3

In the function f(x) = 4(x2 − 6x + ____) + 20, what number belongs in the blank to complete the square?
Savatey [412]
The right answer for the question that is being asked and shown above is that: In the function f(x) = 4(x2 − 6x + ____) + 20, what number belongs in the blank to complete the square?

x2 - 6x + 9

So the answer on the blank space is 9. It should be a perfect square.
= 6/2
= 3^2
= 9

HELP............Graph. y+1=1/3(x−3) (it has to have 2 points)
natta225 [31]
The intercept method of graphing is quick and easy.

Find the x-intercept by setting y = 0 and solving for x:

y+1=1/3(x−3)   =>   0<span>+1=1/3(x−3)
  Multiply both sides by 3:  3 = x - 3.  Then x = 6, and the x-int. is (6, 0).

Find the y-int by setting x = 0 and solving for y:

</span><span>y+1=1/3(0−3)
Mult both sides by 3:  3y+3 = -3, so that 3y = -6, and y = -2.
Then the y-intercept is (0,-2).

Plot these 2 points.  Then draw a line thru them.</span>

Given f'(x) = (x-4)(4-2x), find the x-coordinate for relative maximum on the graph of f(x)
antiseptic1488 [7]

Answer:

The coordinate of the relative maximum is x=4.

Step-by-step explanation:

Given that the derivative of the function f(x) is f'(x) = (x-4)(4-2x), the maxima and minima or the critical points can be found where f'(x)=0, that is:

f'(x) = (x-4)(4-2x)=0.

The solutions to this equation are x=4 and x=2.

Now, if the second derivative f''(x) for a function f(x)  is negative at a critical point, then the critical point is the relative maximum.

Therefore we want to see at which of the two critical points is f''(x) negative. The second derivative is:

\frac{\mathrm{d f'(x)}}{\mathrm{d}x}=f''(x)=-4(x-3).

Now f''(4) is -4, and f''(2) is +4, therefore we deduce that the relative maxium is located at x=4, because there the second derivative f''(x) is negative.
