which statement describes the vertical asymptotes of the graph of $f(x)=\frac{x^{2}-64}{8x - 64}$?\nthe graph has no vertical asymptote.\nthe graph has a vertical asymptote at $x = 8$ only.\nthe graph has a vertical asymptote at $x=-8$ only.\nthe graph has vertical asymptotes at both $x = 8$ and $x=-8$.
Answer
Explanation:
Step1: Recall vertical - asymptote condition
Vertical asymptotes occur where the denominator of a rational function is zero and the numerator is non - zero. Set the denominator equal to zero: $8x - 64=0$.
Step2: Solve the denominator equation
Solve $8x - 64 = 0$ for $x$. Add 64 to both sides: $8x=64$. Then divide both sides by 8, we get $x = 8$.
Step3: Check the numerator at $x = 8$
Substitute $x = 8$ into the numerator $x^{2}-64$. When $x = 8$, $x^{2}-64=8^{2}-64=64 - 64=0$.
Step4: Factor the numerator and denominator
Factor the numerator $x^{2}-64=(x + 8)(x - 8)$ and the denominator $8x-64 = 8(x - 8)$. Then $f(x)=\frac{(x + 8)(x - 8)}{8(x - 8)}=\frac{x + 8}{8},x\neq8$.
Answer:
The graph has no vertical asymptote.
