If the representation is a graph then use the vertical line test. Draw or imagine straight vertical lines going down the graph. If the vertical line only goes through the function line one time then it is a function. For an example, a circle on a coordinate plane is not a function but a wavy line is.
If the representation is a table with points then look at the x values. If x repeats then it is not a function.
silverware* .30 = 36
divide by .30 on each side
silverware = 36/.30
silverware =120
My math teacher said anything to the power of zero is 1
3.071 X10^12. if you move the decimal place to the right 12 times it will end up behind the 3.
