9) 2x¹²-5x²0 -15 20x20 +7x8-54 (9 points) Use the limits to find the horizontal asymptotes of f(x) = - (L'Hospital's Rule is NOT allowed.)

Answer :

The horizontal asymptotes of f(x) are y = 0.

Given function is

f(x) = 2x¹² - 5x²0 - 1520x20 + 7x8 - 54

There is no common factor to remove.To find horizontal asymptotes, determine the highest power of x in the numerator and the denominator.

Here, the highest power of x in the numerator is 20x²0.

The highest power of x in the denominator is also 20x²0.

To find the horizontal asymptote, divide the coefficient of the highest power of x in the numerator by the coefficient of the highest power of x in the denominator which is (2/20) = (1/10).

Therefore, the horizontal asymptotes of f(x) are y = 0.

Horizontal asymptote is a horizontal line that a curve approaches as x (input of the function) tends to +∞ or -∞ (the two infinities).

This line is a horizontal asymptote if, as x becomes very large or very small, the y-value (output) of the function approaches a constant value in the long run.

To find horizontal asymptotes, determine the highest power of x in the numerator and the denominator. Here, the highest power of x in the numerator is 20x²0.

The highest power of x in the denominator is also 20x²0.

To find the horizontal asymptote, divide the coefficient of the highest power of x in the numerator by the coefficient of the highest power of x in the denominator which is (2/20) = (1/10).

Therefore, the horizontal asymptotes of f(x) are y = 0.
