    Small correction at 3:56 the quartic equation should read as x(3-x)(x^2+4x+4) I must have typed a 2x by accident! Sorry 😬

    hey think you made a mistake on 5:46 you said (x+2)(x+2) = x^2+2x+4 it doesn't it is = to x^2+4x+4

      I think he used this formula bro (a+b)^2 = a^2+2ab+b^2 so (x+2)^2 = x^2+4x+4

    at 5:36 how is the solution of the quadratic x+2? if you would add the them coefficient of x would have had to be 4 not 2

      Because there is a negative X in the second bracket so when you times it all out you will have -x^4

    You can think of y=f(-x) as the x is being multiplied by -1 so it still follows the trend of doing opposites as you just divide by -1 to the actual x value for the transformation 👍

    • @jesshenstock7645
      @jesshenstock7645 2 года назад +2

      but in the first bracket the x is negative meaning that the x’s are negative so thta makes the graph negatuve

  • @varunabishek5364
    @varunabishek5364 7 месяцев назад

    At 24:54, the f(-x) is for reflection in y-axis. Similarly, it should have been -f(x) for x-axis. So yeah.
