Answer:

It should be the top left graph where there is point (1,1) and (-1, -1) y = 1/x

Step-by-step explanation:

from the original graph, I see:

f(x) = 2/x because f(2) = 1 = 2/2

f(1/4)= 2/(1/4) = 2

...

so then f(2x) compresses f(x) horizontally by a factor of 2

so f(2x) = 2/(2x) = 1/x

Answer:

$\boxed{\large\sf y = 3x - 5}$

Step-by-step explanation:

Here we are given a equation which is ,

$\longrightarrow y = 3x + 6$

We need to find out the equation of the line which is parallel to the given line and passes through the given point .

And as we know that the slope of two parallel lines are equal .

On comparing the given equation with slope intercept form (y = mx + c )of the line , we have ,

$\longrightarrow m = 3$

Therefore the slope of the parallel line will be ,

$\longrightarrow m_{||}= 3$

Now we can use the point slope form of the line which is ,

$\longrightarrow y - y_1 = m(x - x_1)$

Substitute ,

$\longrightarrow y - 7 = 3 ( x -4)\\\\\longrightarrow y -7 = 3x -12 \\\\\longrightarrow y = 3x -12+7\\\\\longrightarrow y = 3x -5$

This is the required answer .
