Find the domain, vertical asymptotes, and horizontal asymptotes of the function.

Mathematics

Considering the asymptote concept, we have that:

  • The domain of the function is: (-\infty, -8) \cup (-8, 8) \cup (8, \infty).
  • The vertical asymptotes of the function are of x = -8 and x = 8.
  • The horizontal asymptote is of y = 0.

<h3>What are the asymptotes of a function f(x)?</h3>

  • The vertical asymptotes are the values of x which are outside the domain, which in a fraction are the zeroes of the denominator.
  • The horizontal asymptote is the value of f(x) as x goes to infinity, as long as this value is different of infinity.

For this problem, the function is given by:

f(x) = \frac{x}{x^2 - 64}

The vertical asymptotes are the zeroes of the denominator, hence:

x² - 64 = 0 -> x² = 64 -> x = -8 or x = 8.

Hence the domain is:

(-\infty, -8) \cup (-8, 8) \cup (8, \infty).

The horizontal asymptote is the limit of f(x) as x goes to infinity, hence:

y = \lim_{x \rightarrow \infty} \frac{x}{x^2 - 64} = \lim_{x \rightarrow \infty} \frac{x}{x^2} = \lim_{x \rightarrow \infty} \frac{1}{x} = \frac{1}{\infty} = 0

Answer:$3

Step-by-step explanation:

You always divide y by x. In this case 6/2 when you set up a chart. When you do this you get $3 unit rate.

___________=_____

x (unit rate price)   6

Use cross products

The length of a rectangle is 4 more than its width. The area of the rectangle is 21m2 . What is the measure of the width?
iris [78.8K]
Length(l)= 4+ w
Width(w)=w
Area(A)= 21m^2

so keep in mind Area= Length × width

A= l×w
21=(4+w)(w)
21= 4w+ 2w
21=6w
w=3.5

The width is 3.5m

so the answer is about 4m

What are the domain and range of f(x) = 2|x -4|? <br> plz i'm in need
mafiozo [28]

Answer:

Domain: (-∞, ∞)

Range: [0, ∞)

Step-by-step explanation:

The domain represents what x can be. In this scenario, we do not have x as a denominator, and there is nothing limiting x, so its domain is (-∞, ∞)

The range represents what f(x) can be, Because |x-4| is in absolute value, the lowest |x-4| can be is 0, and as a result, the lowest value of 2|x-4| is 2*0=0. The maximum value of f(x) is ∞ as an absolute value does not limit the maximum, making the range [0, ∞)

  • Example-cube

#1

Yes

  • It's cuboid or rectangular prism

#2

No

It has circular shapes ,no sharp edges

#3

No

  • It has a sharp vertice but no staright edges .

#4

Yes

  • It has flat base and sharp edges also staright edges
