The graph of the function f(x) is shown. Which graph represents the function f(2x)
slava [35]

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

Which of the following is a proportion? <br><br> A. 4/6 = 6/9<br><br> B. 5/6 = 10/18
worty [1.4K]
Hey there mate!

Your correct answer would be \left[\begin{array}{ccc}\boxed{\boxed{ 4/6 = 6/9}}\end{array}\right] This would be because 4/6 is almost 1 as a whole, and also, 6/9 is almost 1, as a whole, so this would totally make sense for this to be a proportional.

Hope this helps you budd!
