Question

If f(x) = 2x – 1 and g(x) = log x, compute (f – g) (x).2x – 1 – log x2x – 1 + log xlog x – 2x + 1(2x – 1)log x

Answer 1

Given: Two functions: f(x) = 2x – 1 and g(x) = log x

Required: (f – g) (x)

Explanation:

We need to find difference of two functions.

$(f-g)(x)=f(x)-g(x)$

So

$(f-g)(x)=2x-1-logx$

Final Answer: Option 1 is correct answer.
