Trina borrowed $460 from a friend. Her friend charged her 5% simple annual interest. How much will Trina owe her friend in total after 3 years? Use the simple interest formula to solve. I = prt
I = (460)(0.05)(3)
Trina must pay her friend a total of $.

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.
