First we'll require the derivative (slope) function.
f'(x) = 6x + 1
Next evaluate the derivative function @ x = -2
f'(-2) = 6(-2) + 1
f'(-2) = -11
Thus the slope of the tangent line @ x = -2 is m = -11
Now we can use either y = mx + b or y - y1 = m(x - x1) to find the tangent equation.
y - 4 = -11(x - (-2))
y - 4 = -11(x + 2)
y - 4 = -11x - 22
y = -11x - 22 + 4
Thus
y = -11x - 18 or 11x + y + 18 = 0 is the equation of the required tangent.

Step-by-step explanation:
The formulas jus the top line + the bottom line divided by two then multiplied by the height (dotted line)
Answer:
7
Step-by-step explanation:
<span>I believe the correct answer is option A. A value of greater than 1 is not a possible value of r or the correlation coefficient in statistics. It is a measurement of the direction and strength of relationship between variables. Its value would only have a range of positive one to negative one.</span>
