Consider the function.

matrenka [14]

The correct options are:

a) g(x) = 8*x - 6

b) g(x) = 2x - 10

c) g(x) = 2x - 14

d) g(x) = 8x - 24

<h3>How to identify each transformation?</h3>

Here we have the function:

f(x) = 2x - 6

The proposed transformations are:

a) Stretch by a factor of 4 along the x-axis.

A horizontal stretch of scale factor k is written as:

g(x) = f(x*k).

Then, in this case, we have:

g(x) = 2(x*4) - 6 = 8*x - 6

b) Shift f(x) 4 units down.

A vertical shift of N units is written as:

g(x) = f(x) + N

A shift of 4 units down is written as:

g(x) = f(x) - 4 = 2x - 6 - 4 = 2x - 10

c) Shift f(x) 4 units right.

An horizontal shift of N units is written as:

g(x) = f(x + N).

For a shift of 4 units to the right, we write:

g(x) = f(x - 4) = 2(x - 4) - 6 = 2x - 8 - 6 = 2x - 14

d) A vertical compression of scale factor 1/4.

A vertical compression of scale factor K is written as:

g(x) = f(x)/K

In this case, we will have:

g(x) = f(x)/(1/4) = 4*f(x) = 4*(2x - 6) = 8x - 24

how do you write these equations in slope-intercept form y+1=2x-3 ,2x-3=y+1 , 2y+2=4x-6. Are they the same or different?

inna [77]

y+1=2x-3

y=2x-4

2x-3=y+1

2x-4=y

y=2x-4

2y+2=4x-6

2y=4x-8

y=2x-4

They are all the same: y=2x-4

If 375y=x2 and x and y are positive integers,

Lilit [14]

Answer:

Option d - I and III.

Step-by-step explanation:

Given : If $375y=x^2$ and x and y are positive integers.

To find : Which of the following must be an integer?

Solution :

As we see all option there is a multiple of y.

So, we factoring the number 375

i.e. $375=3\times 5\times 5\times 5$

$375=15\times 5^2$

$375=15\times 25$

In order for 375y to be a perfect square,

The prime factorization of y must contain at least one 3 and one 5.

or y must be a multiple of 15.

If y is a multiple of 15, then $\frac{y}{15}$ must be an integer.

and $\frac{y^2}{25}$ must be an integer.

Therefore, I and III will be correct i.e. option d.
