Rational Function 8Cc5C0
1. The problem is to analyze the function $$f(x) = \frac{5x}{4 - x^2}$$ and understand its behavior.
2. This is a rational function where the numerator is $5x$ and the denominator is $4 - x^2$.
3. Important rules for rational functions:
- The function is undefined where the denominator is zero.
- To find vertical asymptotes, solve $4 - x^2 = 0$.
- To find horizontal asymptotes, compare degrees of numerator and denominator.
4. Solve for vertical asymptotes:
$$4 - x^2 = 0 \implies x^2 = 4 \implies x = \pm 2$$
So, vertical asymptotes at $x = 2$ and $x = -2$.
5. Degree of numerator is 1 (since $5x$), degree of denominator is 2 (since $x^2$ term).
Since denominator degree > numerator degree, horizontal asymptote is $y = 0$.
6. Find x-intercept by setting numerator zero:
$$5x = 0 \implies x = 0$$
So, x-intercept at $(0,0)$.
7. Find y-intercept by evaluating $f(0)$:
$$f(0) = \frac{5 \cdot 0}{4 - 0} = 0$$
So, y-intercept at $(0,0)$.
8. Summary:
- Vertical asymptotes at $x = \pm 2$
- Horizontal asymptote at $y = 0$
- Intercept at origin $(0,0)$
Final answer: The function has vertical asymptotes at $x=2$ and $x=-2$, a horizontal asymptote at $y=0$, and passes through the origin.
