Question

if \\(f(x) = x^4 - x^3 + x^2\\) and \\(g(x) = -x^2\\), where \\(x \
eq 0\\), what is \\((f/g)(x)\\)?

\\(x^2 - x + 1\\)
\\(x^2 + x + 1\\)
\\(-x^2 + x - 1\\)
\\(-x^2 - x - 1\\)

Explanation:

Define the function division

$$ (f/g)(x) = \frac{f(x)}{g(x)} $$

Substitute the given functions

$$ (f/g)(x) = \frac{x^4 - x^3 + x^2}{-x^2},\quad x eq 0 $$

Simplify the expression

$$ (f/g)(x) = \frac{x^4}{-x^2} - \frac{x^3}{-x^2} + \frac{x^2}{-x^2} = -x^2 + x - 1 $$

Answer:

  • (A) \(x^2 - x + 1\)
  • (B) \(x^2 + x + 1\)
  • (C) \(-x^2 + x - 1\) (Correct answer)
  • (D) \(-x^2 - x - 1\)
