Find the five-number summary and draw a box-and-whisker plot for the data set. 130, 110, 121, 141, 137, 136, 103, 144

With out knowing the functions you have to chose form, this could be one.y = 5.00xx = hours worked and y = the money he will earn.

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.
