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(75887) (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)
