ok i dont know how to find the error bound plz help?

(a) Approximatefby a Taylor polynomial with degreenat the numbera.

T2(x) = Enter a mathematical expression.

12+(1/4)*(x-4)-(1/64)*(x-4)^2

(b) Use Taylor's Inequality to estimate the accuracy of the approximationfTn(x)whenxlies in the given interval. (Round the answer to six decimal places.)

i think i find M to be .001953125 to use in the formula (M/(n+1)!)|x-a|^n+1 but i dont know what to do on this anyone help? THANKS!
