Answer:
The correct answer is 0 or choice A on edge
Step-by-step explanation:
right on edge
Therefore, value of r(x) as x approaches Infinity : zero
[tex]\bold{\lim_{x \to \infty} r(x)=0}[/tex]
What is function?
"A function is a special relationship where for each input and their is single outputs."
What is limit?
"Limit is defined as the value that a function approaches for the given input value."
For given situation,
We have been given a function,
r (x) = Start Fraction a x Superscript b Baseline + 8 Over c x Superscript d Baseline End Fraction
We can rewrite it as,
[tex]r(x)= \frac{ax^b+8}{cx^d}[/tex] , where a, b, c, and d are positive integers and b < d.
We need to find the value of r(x) approach as x approaches Infinity.
This means, we need to find the value of the limit [tex]\lim_{x \to \infty} r(x)[/tex]
Now, we find the value of limit for given function.
[tex]\lim_{x \to \infty} r(x)[/tex]
= [tex]\lim_{x \to \infty} \frac{ax^b+8}{cx^d}[/tex]
= [tex]\lim_{x \to \infty} (\frac{ax^b}{cx^d} + \frac{8}{cx^d})[/tex]
= [tex]\lim_{x \to \infty} \frac{a}{cx^(d-b)} + \lim_{x \to \infty} \frac{8}{cx^d}[/tex] ...............(since d > b)
= [tex]0 + 0[/tex]
= [tex]0[/tex]
Therefore, [tex]\bold{\lim_{x \to \infty} r(x)=0}[/tex]
