The petrol consumption of a car (y miles per gallon) depends on the speed the car is travelling at (x mph), according to the formula y= 200-1.5x - 4500/x

a.) draw the graph of this equation for 40 <= x <= 80, taking a scale of 2 cm to 5 units on each axis.
b.) what is the petrol consumption at 75 mph
c.) use your graph to estimate the most economical speed at which to drive this car. ​

"image"

step-by-step explanation:

in most of these problems, the notation is that the point with a "prime" is the image of the point without. that is, b' is the image of b.

here, there is no dilation or reflection. there is simply translation (with no direction shown). which figure you call the "preimage" and which one you call the "image" is up to you. as a matter of convention, the naming is as described above.
