Study Notes
Function Analysis
- A function g(x) is defined as g(x) = x + 2lnx
- The domain of g(x) is 0.75 < x < 0.176
- The function f(x) is defined as f(x) = 1 - x + (1/2)(1 + ln x)
- The derivative of f(x) is f'(x) = -g(x)/x
- f(3) is calculated as 1 - 3 + (1/2)(1 + ln3)
- f(1) is calculated as 1 - 1 + (1/2)(1 + ln1), and ln 1 equals 0; therefore, f(1) = 1/2
- x = 3 is a value
- x = 1 is a value
