Mastery You lean an umbrella against a table. The handle of the
umbrella is 18 cm away from the table and the top of the
umbrella touches the table at a point 60 cm off the ground.
What is the slope of the umbrella? Round your answer to the
nearest hundredths place.

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.
