(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:

Capital formation improves the conditions and methods for the production of a country. Hence, there is much increase in national income and per capital income. This leads to increase in quantity of production which leads to again rise in national income. The World Bank tracks gross capital formation, which it defines as outlays on additions to fixed assets, plus the net change in inventories. Fixed assets include plant, machinery, equipment, and buildings, all used to create goods and services. Inventory includes raw materials and goods available for sale.Oct
