Ok so I can’t answer it but here you goooo:)
We use the graph of

as an example. The graph is shown in the first picture below
Let's take 2 as the value of the constant 'c'
The transformation of

gives the effect of halving the x-coordinates, as shown in the second picture.
The transformation of

, as shown in the third picture, gives the effect of doubling the y-coordinate
In conclusion,

gives the effect of halving the x-coordinates while

gives the effect of doubling the y-coordinates
Answer: 2 < x < 7
Step-by-step explanation:
5/8 x 3/10= 3/16
8/15 x 5/12 x 9/10= 3/5
8/3 x 6/7 x 5/16= 5/7
