Final answer:
The false position method is a numerical technique used to solve equations by narrowing down the range where the root lies through repeated approximation.
The correct answer is 2).
Step-by-step explanation:
The false position method is a numerical method used for solving equations. Specifically, it is a root-finding algorithm that continuously narrows the range of values in which the root of the equation must lie. The method involves using two initial points that lie on opposite sides of the root and formulating a straight line between them. The x-intercept of this line provides an approximation of the root. This process is repeated with the new approximation, refining the result until a sufficiently accurate value is reached. The false position method is not used for finding the value of cd, graphing functions, or calculating derivatives.
