Therefore, divergent thought—the thought process/method used to generate creative ideas by exploring possible solutions—is the only concept that would HELP her complete the task.
To learn never stop and liberate as much as you can
(a)
We have been given an equation
. Upon taking derivative of this equation with respect to x on both the sides, we get:

(b)
In order to write the equation of tangent line, we need to find the slope of the line. We know that point (3,11) lies on the graph. Therefore, we write the slope of the tangent as:

Therefore, equation of tangent line is:

(c)
We know that slope of tangent is given as
. The tangent will be vertical when denominator of slope is zero, that is:
