On a town map, each unit of the coordinate plane represents 1 mile. Three branches of a bank are located at A(-3,1), B(4,2), and C(2,0). A bank employee drives from Branch A to Branch B and then dricas
halfway to Branch C before getting stuck in traffic. What is the minimum total distance the employee
may have driven before getting stuck in traffic? Round to the nearest tenth of a mile if necessary.

sample answer: you can determine whether each element of the domain is paired with exactly one element of the range. for example, if given a graph, you could use the vertical line test; if a vertical line intersects the graph more than once, then the relation that the graph represents is not a function.

large crystals result from very slow cooling.

evaporation of water: this would produce an evaporite which is a sedimentary rock. like a salt pan in a desert. not possible to have volcanic rocks originate this way.

crystalization in molten earth: slow cooling over time. (hundreds to millions of years)

crystalization at earth's surface: this results in fast cooling. (a few hours to a few months or years)

crystalization from cooling off hot water: that would be a hydrothermal deposit. while associated with volcanics they are not volcanic rocks themselves and usually occur fairly rapidly.
