Let f (x )equals x squared and note that Modifying Below lim With x right arrow 2f(x)equals 4. For epsilon equals 1, use a graphing utility to find the maximum value of delta greater than 0 such that StartAbsoluteValue f (x )minus 4 EndAbsoluteValue less than epsilon whenever 0 less than StartAbsoluteValue x minus 2 EndAbsoluteValue less than delta.
