first, covert it into either \(Ax^2 + bx + c = 0 \) or \(f(x) = y = a(x-h)^2 +k \) where \(h, k \) is your vertex and \(a\neq 0\) the first option is easier, the second option requires you to know how to complete the square
nincompoop
  • nincompoop
you can solve the vertex in the first one by using \(\large (x=\frac{-b}{2a},y = f(x)) \)

@nincompoop how would you put y=1/12x^2 in that first formula???
nincompoop
  • nincompoop
so if you have a standard form of \(y = 2x^2 - 4x + 3\) your vertex can be solved by identifying your coefficients a = 2 b = 4 c = 3 vertex \(\large \frac{-b}{2a} = \frac{-(2)}{2(4)} = -\frac{1}{4}\) then plug \(- \frac{1}{4} \) into all of the x in \(y = 2x^2+4x+3 \)

@nincompoop i think i'll just keep trying with youtube because you're confusing me even more
nincompoop
  • nincompoop
analyze the standard form \(y = Ax^2 + Bx +c \) you have three terms first term \(Ax^2 \) second term \(Bx \) third term \(c \)
nincompoop
  • nincompoop
ask yourself if the given equation has second or third term? if they don't show up it means it is zero anything +0 will remain the same
