Select the answer below that best describes the expected behavior of the error in a finite

difference derivative estimator when the stepsize is reasonably large.

Truncation error dominates, reducing the stepsize reduces the error, and the relationship is roughly

linear on a $log-log$ plot.

Truncation error dominates, reducing the stepsize reduces the error, and the relationship is roughly

linear on a log$-$linear plot.

Roundoff error dominates, reducing the stepsize increases the error, and the relationship is roughly

linear on a log$-$linear plot.
