Nonsense. Line in the plane cannot have more than one x-axis intercept. Line cannot have exactly two x-axis intercepts. Only idea is you're trying to describe the whole x-axis; but giving as having two x-axis intercepts is the wrong way to do it.

            The post by @josgarithmetic is  INCORRECT.

            Simply ignore it,  for your safety.

The plot   y = f(x+6)   is the plot  y = f(x)  shifted  6  units to the left.

T H E R E F O R E,   if  8  and  9  are x-intercepts for  f(x),  then

        x-intecepts for  f(x+6)  are   8-6= 2  and   9-6 = 3.


ANSWER.   x-intecepts for  f(x+6)  are  2  and  3.
