Step 1 :To find the vertical asymptotes of a rational function, we set the denominator equal to zero and solve for x. This is because the function is undefined at these x-values, creating a vertical asymptote.
Step 2 :For the given function \(H(x)=\frac{x^{3}-64}{x^{2}-7 x+12}\), the denominator is \(x^{2}-7 x+12\). Setting this equal to zero gives us \(x^{2}-7 x+12=0\). Solving this equation gives us the vertical asymptotes at \(x = 3\) and \(x = 4\).
Step 3 :To find the horizontal asymptotes of a rational function, we compare the degrees of the numerator and denominator. If the degree of the numerator is less than the degree of the denominator, the x-axis (y = 0) is the horizontal asymptote. If the degrees are equal, the horizontal asymptote is the ratio of the leading coefficients. If the degree of the numerator is greater than the degree of the denominator, there is no horizontal asymptote.
Step 4 :For the given function \(H(x)=\frac{x^{3}-64}{x^{2}-7 x+12}\), the degree of the numerator is 3 and the degree of the denominator is 2. Since the degree of the numerator is greater than the degree of the denominator, there is no horizontal asymptote.
Step 5 :To find the oblique asymptotes of a rational function, we perform long division of the numerator by the denominator. If the degree of the numerator is exactly one more than the degree of the denominator, the quotient is a linear function which is the equation of the oblique asymptote.
Step 6 :For the given function \(H(x)=\frac{x^{3}-64}{x^{2}-7 x+12}\), the degree of the numerator is 3 and the degree of the denominator is 2. Since the degree of the numerator is exactly one more than the degree of the denominator, there is an oblique asymptote. Performing long division of the numerator by the denominator gives us the oblique asymptote at \(y = x + 7\).
Step 7 :Final Answer: \(\boxed{\text{The function has two vertical asymptotes at } x = 3 \text{ and } x = 4. \text{ The function has no horizontal asymptote. The function has one oblique asymptote at } y = x + 7.}\)
