3. (a) (15 Points) Write a function called derivative which takes three input parameters f,a and h and returns the difference formula hf(a+h)f(a) which is a approximation for f(a) with step size h. (b) (10 Points) In python, use the derivative function to compute the value f(5) of the function f(x)=x2+x+1
