Question

The graph of the function f(x) is shown. Which graph represents the function f(2x)

Answer 1

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
