Given the following table:

x	0.0026	0.0027	0.0028	0.0029	0.003
f(x)	0.00260676	0.00270729	0.00280784	0.00290841	0.003009

Use the table to find the largest $\delta$ so that $\vert f(x)-f(0.0028)\vert <0.00027$ when $\vert x-0.0028\vert < \delta$.
$\delta =$

To obtain more precise information about the value of $f$ near $0.0028$ enter a new increment value for $x$ here and then press the Submit Answer button.

Your answer must be within $1e-05$ of the correct answer.
