Question
Set $f(x)=2 x^{2}-3 x+1$ and $g(x)=x^{2}+1 / x$ Calculate the indicated value.$$(f-g)(-1)$$
Step 1
Given that $f(x) = 2x^2 - 3x + 1$ and $g(x) = x^2 + \frac{1}{x}$, we subtract $g(x)$ from $f(x)$ to get: \[(f-g)(x) = 2x^2 - 3x + 1 - (x^2 + \frac{1}{x}) = x^2 - 3x - \frac{1}{x} + 1.\] Show more…
