D because the sum of 2 sides of a triangle have to be greater than the 3rd side so 7+4 is the only option where the sum of both sides will be greater than the 3rd side
Min at (2,-4)
D=1-4*1*-6=25=> 2 real roots
x=3, -2
f(x) = (x - 2)^3 + 1
Find the derivative:-
f'(x) = 3(x -2)^2 This = 0 at the turning points:-
so 3(x - 2)^2 =
giving x = 2 . When x = 2 f(x) = 3(2-2)^3 + 1 = 1
Answer is (2, 1)
Answer:
you cant send pictures unless created on a graphing website but ill try to help. you first have to simplify y, and if you could comment a clearer equation that would be nice because your equation is confusing(cant tell if its all together
