Which of the following is true about horizontal asymptotes?

a.) A function has a horizontal asymptote at the value of y = a if the line y = a can be used to estimate the end behavior of a function and if f ( x ) → a as x → ∞ or x → − ∞ .

b.) All horizontal asymptotes describe what happens when x gets close to 0 .

c.) All rational functions have at least one horizontal asymptote.

d.) All horizontal asymptotes describe what happens when the denominator's value gets close to 0.

Respuesta :

A  function has a horizontal asymptote at the value of y = a if the line y = a can be used to estimate the end behavior of a function and if f ( x ) → a as x → ∞ or x → − ∞  is the correct statement about horizontal asymptotes. Option A

What are horizontal asymptotes?

A horizontal asymptote of a graph can be defined as a horizontal line at  y = b where the graph tend to approach the line as an inputs approach to infinity ( ∞ or –∞).

A slant asymptote of a graph is known as a slanted line y = mx + b where the graph approaches the line as the inputs approach the positive infinity ∞ or  to the infinity –∞.

Thus, a function has a horizontal asymptote at the value of y = a if the line y = a can be used to estimate the end behavior of a function and if f ( x ) → a as x → ∞ or x → − ∞  is the correct statement about horizontal asymptotes. Option A
