Which statement correctly compares the graphs of the functions?
As the values of x increase, g (x) will eventually be greater than f (x).
As the values of x increase, f (x) will eventually be greater than g (x).

value of the y-intercept of y = g (x).
The value of the y-intercept of y = g (x) is greater than the
value of the y-intercept of y = f (x).
