“f(x) means y”: Students’ meanings for function notation
Page: 981
When using function notation, some students describe f(x) as meaning the same thing as the variable y to represent the output value of the function. This paper describes interviews with two students with vastly different interpretations of function notation. The interviews were designed to explore how students interpret function notation when it is used to represent the output for a given input.
