What are the vertical and horizontal asymptotes for the function f(x)=x^2+x-6/x^3-1
2 answers:
Answer:
vertical asymptote at x = 1
horizontal asymptote at y = 0
Step-by-step explanation:
WE factor both top and bottom
x^2 + x-6 can be factored as (x+3)(x-2)
Now we factor x^3 -1
x^3-y^3= (x-y)(x^2+xy+y^2)
x^3 - 1^3=(x-1)(x^2+x+1)
replace the factors
To find vertical asymptote , we set the denominator =0 and solve for x
x^3 -1 =0
x^3 = 1
Now take cube root
x = 1
So vertical asymptote at x=1
To find horizontal asymptote we look at the degree of numerator and denominator
Degree of numerator =2 and degree of denominator = 3
Degree of numerator is smaller than the degree of denominator so horizontal asymptote at y=0

Answer:
Step-by-step explanation:
We can write a rational function.
We need to make sure our denominator both have zeroes at 3 and 10.
Set an equation equal to zero to find the function
So we would represent that's as
and
Multiply the two binomial together.
Let our numbetator be any interger.
Use any equation as long as the quadratic is the denominator and the interger is the numerator.
Answer:
Step-by-step explanation:
Given:
Width of average grain of salt is,
Width of Rhinovirus is,
Now, expressing each width in scientific notation form, we get:
Now, in order to get how many times 'W' is wider than 'w', we divide the two widths. This gives,
Therefore, the grain of salt is wider than Rhinovirus.
