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)

Complete the square to solve the equation below

frutty [35]

$x^2+x= \frac{7}{4}$

Take one-half of the coefficient of x and square it, then add it to both sides.

$x^2+x+ (\frac{1}{4}) =\frac{7}{4}+ (\frac{1}{4})$

$x^2+x+(\frac{1}{4})= 2$

$\left(x+\frac{1}{2}\right)^2=2$

$x+\frac{1}{2}=\pm \sqrt{2}$
-----------------------------------------------------------------
$x+\frac{1}{2}=- \sqrt{2}$
$x=-\frac{1}{2}- \sqrt{2}$ <=

AND

$x+\frac{1}{2}= \sqrt{2}$
$x= \sqrt{2}-\frac{1}{2}$ <=

Solve 22 = - 3d + 1. Show your steps.

sattari [20]

22 - 1 = -3d
21= -3d
21/-3= d
-7 = d

Bring the 1 to the other side by doing the opposite sign, so subtract 1. Solve the left side.

Bring the 3 to the other side by doing the opposite sign, so divide 21 by -3.

End with D equaling -7
