20. What is the order of rotational symmetry for each design (i. e. what is the angle of rotation to create the rotational symmetry)?

Will give let f(x)=2x and g(x)=[tex]2^{x}[/tex] graph the functions on the same coordinate plane. what are the solutions to the equation f(x)=g(x) ? enter your answers in the boxes x=[? ] or x=[? ]
