Answer:

  B.  3

Step-by-step explanation:

If all you want is a numerical result, sometimes a graphing calculator can provide that easily. The attachment shows it calculates the slope at x=4 to be 3.

  dy/dx = 3 at x = 4

__

The derivative of the expression can be found from the quotient formula:

  d(u/v) = (du·v -u·dv)/v²

  y' = ((x -2)(2x -7) -(x^2 -7x +2)(1))/(x -2)^2

  = (2x^2 -11x +14 -x^2 +7x -2)/(x -2)^2

  = (x^2 -4x +12)/(x -2)^2

  = ((x -4)x +12)/(x -2)^2

Then for x=4, we have ...

  y' = 12/4 = 3

  dy/dx = 3 at x = 4

Answer:

  • No, there is no proportional relationship

Step-by-step explanation:

<u>The proportional relationship is:</u>

  • y = kx, which is a special form of linear equation, with zero y-intercept

<u>In the given case we have:</u>

  • y = 4.5x + 10

This is a linear function but not proportional relationship because it has y-intercept, different than zero
