a) The instantaneous level of alter of a function at level (a, fa) can be determined by formula limh→0fa+h-fah. First, determine the ideals of f(a) andf(a+h). Next, substitute the values worked out into the formula and simplify. Once performed, let h=0 and replacement into the basic equation to find the instantaneous rate of alter of a function.

Alternatively, the formula fa+h-faa+h-a can be used to identify the fast rate of...
