Gomez weighed three containers of sand for a science project. The first container weighed 19.28 grams, the second container weighed 25.3 grams, and the third container weighed 46.3 grams. How much more did the third container weigh than the first and second containers combined?

I'm not sure but i think it's 1670km/h

The answer is (a) 12-2(-1)(6)2(6)=12

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.
