Given that (5,6) is on the graph of f(x), find the corresponding point for the function 4f(x)

Anvisha [2.4K]

Answer:

The corresponding point for the function 4f(x) is (5 , 24)

Step-by-step explanation:

* Lets revise some transformation

- A vertical stretching: is the stretching of the graph away from

the x-axis

- A vertical compression: is the squeezing of the graph toward

the x-axis.

• if k > 1, the graph of y = k • f(x) is the graph of f (x) vertically

stretched by multiplying each of its y-coordinates by k.

• if 0 < k < 1 (a fraction), the graph is f (x) vertically compressed

by multiplying each of its y-coordinates by k.

* In our problem:

- Point (5 , 6) is on the graph of f(x)

- The function will be 4f(x), that means vertical stretching

or vertical compression

∵ k = 4

∵ 4 > 1

∴ It is a vertical stretch

∴ We will multiply the y-coordinate by 4

∴ y' = 4 × 6 = 24

* The corresponding point for the function 4f(x) is (5 , 24)

What is the perimeter of triangle ABC round each step by the nearest 10th see image. Thanks so much

Greeley [361]

Perimeter of the triangle ABC is 18.7 units.

Coordinate of the point A is (4, -1), B is (-1, 4) and C is (0, -3).

Length of the side AB = $\sqrt{(x_{2}-x_{1})^{2}+(y_{2}-y_{1})^{2}}$

AB = $\sqrt{(-1-4)^{2}+(4+1)^{2}} =\sqrt{50}$

AB = 7.07 units = 7.1 units ( rounded to the nearest 10th)

Length of the side BC = $\sqrt{(x_{2}-x_{1})^{2}+(y_{2}-y_{1})^{2}}$

BC = $\sqrt{(0+1)^{2}+(-3-4)^{2}}$

BC = $\sqrt{50}$

BC = 7.07 units = 7.1 units ( rounded to the nearest 10th)

Length of the side CA = $\sqrt{(x_{2}-x_{1})^{2}+(y_{2}-y_{1})^{2}}$

CA = $\sqrt{(4-0)^{2}+(-1+3)^{2}}$

CA = $\sqrt{20}$

CA = 4.47 units = 4.5 ( rounded to the nearest 10th)

Perimeter of the triangle ABC = sum of all three sides = (7.1 + 7.1 + 4.5) units = 18.7 units

Find the horizontal asymptote of the graph of y = -4x^6 + 6x + 3/8x^6 + 9x + 3

Llana [10]

Option B : $y=-\frac{1}{2}$ is the horizontal asymptote.

Explanation:

The function is $y=\frac{-4 x^{6}+6 x+3}{8 x^{6}+9 x+3}$

The horizontal asymptote can be determined by

$y=\frac{leading \ coefficient \ of \ numerator}{leading \ coefficient \ of \ denominator}$

Thus, from the function, the leading coefficient of numerator is -4

The leading coefficient of denominator is 8

Thus, substituting the values in the formula $y=\frac{leading \ coefficient \ of \ numerator}{leading \ coefficient \ of \ denominator}$ , we get,

$y=\frac{-4}{8}$

Dividing, we get,

$y=\frac{-1}{2}$

Thus, the horizontal asymptote is $y=\frac{-1}{2}$

Hence, Option B is the correct answer.
