Best ResponseYou've already chosen the best response.1Would that be: f(x) = 3*(x − 1)*(x − 1) + 2 ?

Best ResponseYou've already chosen the best response.0well it i this; f(x) = 3(x − 1)^2 + 2 sorry

Best ResponseYou've already chosen the best response.1The vertex form of a parabola is given as \( y = a (xh)^2 + k \) where the point \( (h,k) \) is the vertex so comparing the two: \(y=3(x1)^2 +2\) and \(y=a(xh)^2+k\) can you tell me what you think the vertex is? :)

Best ResponseYou've already chosen the best response.1Hmm, it seems sleepyhead is trying another approach, I multiplied it out: f(x) = 3*(x − 1)*(x − 1) + 2 equals 3 * x^2 2x +1 +2 equals 3 x^2 2x +3

Best ResponseYou've already chosen the best response.1I mean as a point :P or tell me h = k = that's ok too

Best ResponseYou've already chosen the best response.1yes, as it asks for the vertex  I assumed it would be easier to point it out since it is already in "vertex form" @wolf1728 :)

Best ResponseYou've already chosen the best response.0these are my choices: The vertex is (1, 2), the domain is all real numbers, and the range is y ≥ 2. The vertex is (1, 2), the domain is all real numbers, and the range is y ≤ 2. The vertex is (–1, 2), the domain is all real numbers, and the range is y ≥ 2. The vertex is (–1, 2), the domain is all real numbers, and the range is y ≤ 2.

Best ResponseYou've already chosen the best response.0Given the functions f(x) = 3x2, g(x) = x2 − 4x + 5, and h(x) = –2x2 + 4x + 1, rank them from least to greatest based on their axis of symmetry.

Best ResponseYou've already chosen the best response.0these are my choices:) thanks for the help f(x), g(x), h(x) f(x), h(x), g(x) g(x), h(x), f(x) g(x), f(x), h(x)

Best ResponseYou've already chosen the best response.1the axis of symmetry is given by \( \large x = \frac{b}{2a}\) when the equations are in a form \(y=ax^2+bx+c\)

Best ResponseYou've already chosen the best response.1I made a mistake on previous problem f(x) = 3*(x − 1)*(x − 1) + 2 equals 3 * (x^2 2x +1) +2 equals 3 x^2 6x +5
