The equation for the pH of a substance is pH = -log[1], where H+ is the concentration of hydrogen
ions. What is the approximate pH of a solution if the concentration of hydrogen ions is 5.0 x 10-4 moles
per liter?
2.7
3.0
3.3
3.6

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.
