Answer:
The value of function at x = 2 is 8.
Step-by-step explanation:
Given : Function 
We have to find the value of given function at x = 2 , that is f(2)
Consider the given function 
To find the value f(2) put x = 2 in given function ,
We have,

Simplify, we have,

Simplify further, we have,

Thus, the value of function at x = 2 is 8.
4th quadrant is positive x (cos) and negative y (sin)
Use the Pythagorean Theorem to calculate the value of y (sin).
x² + y² = c²
5² + y² = 13²
25 + y² = 169
y² = 144
y = 12
Since the y-value is negative in the 4th quadrant, then y = -12
Answer:
= 14X + 6
