Function or not? For every input (value between the parentheses), find the output using the given function. Secondly, tell whether the relation is a function or not. Remember that if the same input has two different outputs, the relation is not a function.
Ex: {(2, 14), (3, 16), (4, 14), (5, 16), (2, 20)}
Did you notice that 2 has two outputs: 14, and 20..
Note that if two inputs have the same output, the relations is a function:
Ex: {(2, 14), (3, 16), (4, 14), (5, 18), (6, 20)}, Example f(x) = √ + Domain is only the positive real numbers
f(1) = √ + = √ + = √
f(0) = √ + = √ + = √ = 1
f(3) = √ + = √ + = √

Let us imagine that the number of automobile accidents in a certain region are related to the regional number of registered automobiles in tens of thousands (b1), alcoholic beverage sales in $10,000 (b2), and decrease in the price of gasoline in cents (b3). furthermore, imagine that the regression formula has been calculated as: y = a + b1x1 + b2x2 + b3x3 where y = the number of automobile accidents, a = 7.5, b1 = 3.5, b2 = 4.5, and b3 = 2.5 calculate the expected number of automobile accidents for a football weekend if the region has 25,000 registered vehicles, $75,000 worth of beer is sold, and a gas war causes a 10 cent drop in a gallon of gas.
