The correct Answer is:
To solve the problem, we need to evaluate the expression \((f(x) + g(x)) / (f(-x) - g(-x))\) at \(x = 2\), where \(f(x) = x^2\) and \(g(x) = \frac{1}{x^3}\). ### Step-by-Step Solution: 1. **Calculate \(f(2)\)**: \[ f(2) = 2^2 = 4 \] 2. **Calculate \(g(2)\)**: \[ g(2) = \frac{1}{2^3} = \frac{1}{8} \] 3. **Calculate \(f(-2)\)**: \[ f(-2) = (-2)^2 = 4 \] 4. **Calculate \(g(-2)\)**: \[ g(-2) = \frac{1}{(-2)^3} = \frac{1}{-8} = -\frac{1}{8} \] 5. **Substitute values into the expression**: \[ f(2) + g(2) = 4 + \frac{1}{8} = \frac{32}{8} + \frac{1}{8} = \frac{33}{8} \] \[ f(-2) - g(-2) = 4 - \left(-\frac{1}{8}\right) = 4 + \frac{1}{8} = \frac{32}{8} + \frac{1}{8} = \frac{33}{8} \] 6. **Evaluate the final expression**: \[ \frac{f(2) + g(2)}{f(-2) - g(-2)} = \frac{\frac{33}{8}}{\frac{33}{8}} = 1 \] ### Final Answer: The value of \(\frac{f(x) + g(x)}{f(-x) - g(-x)}\) at \(x = 2\) is \(1\).
