If the point (-1,2) lies on the graph of y=f(x), then a point on the graph of y=-2f(x)+5

(-1, 1)

Step-by-step explanation:

Multiply f(x) or y value by -2, so (-1, 2) -> (-1, -4)

Add 5 to the f(x) or y value since it is a vertical translation, so (-1, -4) -> (-1, 1)

glide reflection.

its mainly because the pattern will be infinite and will never end. it will look like a gilder or like a filpbook when set to motion.

ratio is 2 : 9

the answer is three

13.5 : 3
