Use the formuala | Error | ≤ M 2 ( x − a ) 2 , {\displaystyle |{\text{Error}}|\leq {\frac {M}{2}}(x-a)^{2},} where M > 0 {\displaystyle M>0} , to estimate an error bound for your approximation of 7 3 {\displaystyle {\sqrt[{3}]{7}}} from part (a). It will be useful to remember how to find such an M . {\displaystyle M.}
