QuestionUse the graph of $f(x)=\frac{5}{x^{2}+1}$ to solve the inequality $\frac{5}{x^{2}+1} \leq 1$. a) $x= \pm 2$ b) no solution C) $-2 \leq x \leq 2$ d) $x \leq-2, x \geq 2$

Studdy Solution
Interpret the solution to determine the correct answer choice:
The solution $x \leq -2$ or $x \geq 2$ matches choice d).
The correct answer is:
$$\boxed{\text{d) } x \leq -2, x \geq 2}$$
