What are the vertical and horizontal asymptotes for the function f(x)=3^2/x^-4
Zarrin [17]

The vertical asymptotes x = - 2, 2 and Horizontal asymptotes y = 3

Option A is the correct answer.

<h3>What are Function?</h3>

Function are mathematical statement which links an independent variable to dependent variable.

It always comes with a defined domain and range.

The equation mentioned is incorrect in the question w.r.t. to the solutions mentioned, The right equation is

\rm f(x) = \dfrac{3 x^2}{x^{2}-4}

This function can also be written as

\rm f(x) = \dfrac{3 x^2}{x^{2}-2^2}\\\\\rm f(x) = \dfrac{3 x^2}{(x+2)(x-2)}

Vertical asymptotes are defined when the denominator of a rational function tends to zero.

To find the equation/s let the denominator equal zero.

Denominator tends to zero for x = -2 and x = +2

Horizontal Asymptote is when the function f(x) is tending to zero.

for x = +∞ and x = - ∞

Let the rational function f(x)= \dfrac{mx^a}{nx^b}  where  and a and b are degree of numerator and denominator.

If a < b , then the y axis y = 0 is a horizontal asymptote.

If b = a then horizontal asymptote is the line y = p/q

Here the value is b = 2 and a = 2

Since b = a the horizontal asymptote is the line

y = m/n  where m = 3 and n = 1

Therefore y = 3

So , vertical asymptotes x = - 2, 2

Horizontal asymptotes y = 3

Option A is the correct answer.

Can someone please answer this question and please answer it correctly please show work please i need it please help
serg [7]

Answer:

14. 1 inch = 96 miles (12 × 8)

1/2 inch = 48 miles (96 ÷ 2)

96 + 48 = 144 miles

3 3/4 = 3.75

144 ÷ 3.75 = 38.4

A. 38.4 mph

15. Adding a negative number is the same as just subtracting.

D. 35(2) - 1/2(15)

20. - = withdrew because you are subtracting

+ = deposited because you are adding

D. Peter withdrew $47.27 and deposited $598, increasing his bank account by $550.73

21. Yana: 7 - 3 + 6 - 1 + 8 - 2 = 15

15 ÷ 6 = 2.5 average

Amber: 1 + 5 - 2 + 4 - 2 + 6 = 12

12 ÷ 6 = 2 average

2.5 - 2 = 0.5

A. Yana's average number of points is 0.5 point greater than Amber's
