Hi all , any one can help me?
the connection between the real roots of a rational equation and the x-intercepts of the graph of the corresponding rational function, and describe this connection.
how can I explain that?
They are the same
the roots of f(x) are the x values that make f(x)=0
The equation of the x axis is y=0
so the roots of the equation y=f(x) are the x values that make f(x)=0 true
