    One trick for searching the vertex of parabola just take bit a second and the two types of parabola opening upward or downward
    Theirs vertex should b lies Thier maximum or minimum point so just take the first derivative of giving equation and put equal to zero that give u X intercept of vertex by putting X intercept in original equation u can easily obtained corresponding y intercept

      Dear alkaiser hasim, we are using the well known fact: vertex form of a Parabola is:
      y=a(x - h)^2 + k. Now in our example, we have y=2(x + 1)^2 - 3 => it can also be written as y=2(x - (-1))^2 + (-3) => by comparing with the vertex form => a=2, h=-1, k=-3. All the best :)

    • @Mediterranean81

      maybe because the discriminant is equal to zero

    • @cleteikeda8402
      @cleteikeda8402 4 роки тому +1

      (x-h) is the formula. This part of the equation reads (x+1); all that means is that is really looks like this (x - -1) or x minus negative one. To subtract a negative you are really adding a positive.....keep, change, change.
