Given equation is
Now it says to find f(2)
that simply means plug x=2 because we see that 2 is written in place of x in f(x) and f(2)
Hence final answer is
Given:
A figure of a circle. A secant and tangent of the given circle.
To find:
The correct equation.
Solution:
According the intersecting tangent secant theorem, the square of tangent is equal to the property of external segment of secant and the measure of the secant.
Using intersecting tangent secant theorem, we get
It can be written as
The required equation is .
Therefore, the correct option is B.
