Can we plot graphs over really small intervals?

I know  the function

f[x_] := 10 x^4 + Log[2 - x];

has a zero in the interval [2 - 10^(-69), 2 - 10^(-70)]
but I cannot draw the graph of f over that interval.
Mathematica says that x  in  {x, 2 - 10^(-69), 2 - 10^(-70)}
must have distinct numerical values.
