    please help I'm really confused, for x^2 + 2x-8 you drew the minimum point at y=-8 as this fits for when x=0, but by completing the square, the turning point is -1,-9 not -1,-8 and I also checked on a graph plotter and the minimum is at -9. HELP please!!!

      Please play the video back from 7:00 and you will see that I mention about a common mistake. I hope this will sort the problem out for you. You are correct in your thinking but you need to play the video back again to appreciate the point I was making. I hope it ends any confusion for you.

    what happens if, when you factorise the equation, both of the numbers after x are the same?

    • @ExamSolutions_Maths
      @ExamSolutions_Maths  3 роки тому

      This is known as a double root and the sketch would be a parabola which would flick up or down at that root. Just like the y=x^2 sketch.

    Can someone please explain why f(x+1) moves the parabola to the left, down into the negatives, instead of right into the positives????????>

    • @GreenTornado
      @GreenTornado 7 років тому

      the medium cheese I am not sure if it is correct, but I believe it's because, if you solve for x (x+1=0), you get x=-1. Negative numbers go in the left direction on a number line, and that's why something like "f(x+1)" moves the parabola to the left.

    • @ExamSolutions_Maths
      @ExamSolutions_Maths  9 років тому

      You will notice in most questions you will be asked to mark on the y-intercept. It is an important and easy point to find when sketching graphs.
