The amount of Carbon-14 in a wooden spoon found at an archeological site is 2.1 grams. Spoons of this type are known to contain 10 grams of Carbon-14 at their time of creation, and the amount of Carbon-14 x years after the creation of this artifact is modeled by C(x) = 10 times (0.5)t the power of n over 5730. How many years ago was this spoon made? A 27,285.1 years B 12,901.4 years C 2,641.5 years D 6,133.3 years

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.
