The -4 will translate the graph of f(x) 4 units to the right. Then the -2 before the x will stretch it vertically with factor 2, then reflect it in the y -axis. Finally the + 5 will translate the graph 5 units vertically upwards
You can think of an hour and a half as 75% itself already because you have 3/4 or three thirty minute periods. So every 1/4 is a 30 minute period, and if you multiply 1/4 by 4 you get 4/4 which you ten can convert to 2 hours or 4, 30 minute time periods. (I’m sorry if I explained this in a very confusing manner). It will take Amelia 2 hours in total to finish her drawing.
