F(x) = 3x^2 +12x+7 in standard form
ivann1987 [24]

Answer:

y = ax^2 + bx + c  =>  F(x) = 3x^2 +12x+7;   F(x) = 3x^2 +12x+7 is already in standard form for the equation of a parabola.

Step-by-step explanation:

Actually, F(x) = 3x^2 +12x+7 is already in standard form, y = ax^2 + bx + c.  Double check the instructions for this problem.  Did you perhaps want "vertex form?"
