“…One can approach the study of functions from the correspondence view or the covariation view (Confrey & Smith, , ; Ellis, Ozgur, Kulow, Dogan, & Amidon, ). The correspondence view is concerned with the dependence of outputs on inputs, while the covariation view is concerned with representing the nature of change (e.g., linear functions represent constant change).…”

“…Mental activities to reverse mathematical concepts are important at all levels of mathematics (e.g., addition and subtraction of the whole number, differentiation and integration in calculus, exponent and logarithm, function and inverse function) (Ellis, Ozgur, Kulow, Dogan, & Amidon, 2016;Haciomeroglu, Aspinwall, & Presmeg, 2010;Ramful, 2014;Simon, Kara, Placa, & Sandir, 2016). Some researchers have explained reversible reasoning in addition and multiplication (Hackenberg, 2010;Steffe & Olive, 2010); however, reversible reasoning in the function domain has not been given much attention.…”

“…La función exponencial ha sido objeto de estudio en diversas investigaciones, las cuales se han realizado desde diferentes enfoques: registros de representaciones semióticas (Castro et al, 2017;Sureda & Otero, 2013); aplicaciones de las funciones exponenciales (Sastre et al, 2017); desarrollo del razonamiento covariacional (Ellis et al, 2016;Trejo & Ferrari, 2018), y diseños de actividades con tecnología (Castillo et al, 2013), entre otros.…”

“…Entre las investigaciones que se han enfocado en estudiar el desarrollo del razonamiento covariacional exponencial (tercer grupo) está la realizada por Ellis et al (2016) quienes presentan una Trayectoria de Aprendizaje de Crecimiento Exponencial que identifica y caracteriza las actividades iniciales para desarrollar la comprensión del crecimiento exponencial como resultado de un énfasis de instrucción en la covariación a partir de dos experimentos de enseñanza. Como resultado de su investigación, obtuvieron que los estudiantes logran reconocer el crecimiento exponencial encontrando el factor de crecimiento y la relación funcional = .…”
