well,
f(40) = 3
8f(8x) = 8f(320)
Unfortunately, know f(40) tells us nothing about f(320).
I think you have left out something.
If the point (40,3) is on the graph of y=f(x), what point must be on the graph of y=8f(8x)?
The point (?,?) must be on the new graph.

Describe the effect that the transformations y=8f(8x) have on the graph of y=f(x).
shrink horizontally by a factor of 8
stretch vertically by a factor of 8
If you think on it a bit, you should see why. Try using some online grapher to experiment.
