Q. QuestionFind all horizontal asymptotes of the following function.f(x)=10x2−56x+64x−4
Compare degrees: To find the horizontal asymptotes of a rational function, we need to compare the degrees of the numerator and the denominator. If the degree of the numerator is less than the degree of the denominator, the horizontal asymptote is y=0.
Identify numerator degree: The degree of the numerator, which is the highest power of x in the numerator, is 1 (since the numerator is x−4).
Identify denominator degree: The degree of the denominator, which is the highest power of x in the denominator, is 2 (since the denominator is 10x2−56x+64).
Determine horizontal asymptote: Since the degree of the numerator 1 is less than the degree of the denominator 2, the horizontal asymptote of the function is y=0.
Final result: Therefore, the function f(x)=10x2−56x+64x−4 has one horizontal asymptote, which is y=0.
