Hi i need help with the following question:

The point(1,4) is on the graph of y= f(x). Determine the coordinates of the image of this point on the graph of y=3f[-4(x+1)]-2.

What i tried was plunging in 4 for y and 1 for x and solving for the image but i did not get the correct answer which is (-5,10) from my book.

Edit: what does it mean by "image" ?
