 Question 420620: I need help with this please :) equation is f(x)= x^2 - 4x - 3 a)Graph y=f(x) in the standard viewing rectangle. b)approximate the coordinates of each turning point. c)estimate any local extrema.Answer by stanbon(60771)   (Show Source): You can put this solution on YOUR website!f(x)= x^2 - 4x - 3 a)Graph y=f(x) in the standard viewing rectangle. -------------------------------- b)approximate the coordinates of each turning point. The minimum occurs where x = -b/(2a) = 4/2 = 2 f(2) = 2^2-4*2-3 = -8 minimum at (2,-8) -------------------------- c)estimate any local extrema. (2,-8) ================= Cheers, Stan H.
