Summary
Functions of both graphs are identical on calculator.
On my graphing calculator y = 2x/3x gives precisely the same graph as y = 2/3x squared. How is this possible?

Multiplications and divisions should be evaluated from left to right. 2x/3x = (2x/3) x = (2/3) x^2

If you want the calculator to graph ##y = \frac{2x}{3x}##, write it as y = (2x)/(3x)

Thanks. Much appreciated.
