What’s a real life example of dilation for geometry?

The pupil of the eye can dilate. Pupils dilate if you are in darker locations to let more light enter the eye for site. However, if the pupils are very dilated, even when a light is shined on the eye, this indicates something is wrong with the patient. Pupil dilation is measured in millimeters.

First locate the turning point (vertex) of the graph. which is at the coordinates x=5 and y=9 or (5; 9).to determine whether it's a maximum or mininum value, you have to discern whether the vertex's y-value is the highest value or lowest value the graph can reach. since the vertex's y-value, 9 is the highest value the graph can reach, it will be a maximum.another basic way to determine whether the vertex's value is max or min is to see if the graph is smiling or sad. if it's smiling, the turning point/vertex would be a minimum, while a sad parabola would have a maximum y-value at the vertex.
