Unformatted text preview: 1-1 FunctionsTwo ways to describe or define functionsNote the functions defined on p. 13:Cost function: C = (fixed costs) + (variable costs)C = a + bxE. g. C = 3000 + 200xThis is an example of a function defined by an equation, with•independent variablex•dependent variableCWhen graphing such a function•the independent variable labels the horizontal axis•the dependent variable labels the vertical axisAlternatively, the Cost function could have been given asC(x) = 3000 + 200xThis is a function defined using functional notation. Here, the “C” is the name of a function, not the name of a variable, as in the prior example.The independent variable is still x, but there is no dependent variable, so you can label the vertical axis with “C(x)”.Using this notations, we can write:C(1000) = 3000 + 200(1000) = 203000That is, the cost of producing 1000 units is $203,000.00The 1000 is called an input, with corresponding output 203000....
