El ingreso mensual por concepto de la venta de x unidades de cierto artículo está dado por I(x) = -0.01x² + 12x dólares. Determine el número de unidades que deben venderse cada mes con el propósito de maximizar el ingreso.

¿Cuál es el correspondiente ingreso máximo?

¿Cuando el ingreso será cero?

D. y = x^2

Step-by-step explanation:

Linear functions are functions in which the power of the unknown variable is 1 , that is the other of the unknown variable will be 1

A. y = x

This is a linear function because both x and y has 1 has their power

B. y = 2x

This is also linear

C. y = x + 2

This is also linear

D. y = x^2

This is not linear , although the power of y is 1 but the power of x is 2 , for it to be linear , the highest power of the unknown must be 1
