Let f(x)=2.912345x^2+3.131579x-0.0
(a) to simplify approximation of f, write a quadratic function g(x) with integer coefficients that closely models f(x) for -10 < x < 10.
(b) compute g(4) and f (4)
(c) compute the error in using g (4) to approximate f(4) as a percentage of the correct answer f(4)
(d) for larger values of x (say x = 10 or x = 20), would g (x) be an overestimate or an underestimate of f (x)? justify your answer without computing specific values of f and g.
