    Q10a on this file (http://www.mattsrevision.com/wp-cont...-Solutions.pdf) says that the curve touches the x axis at x=0. Does this always apply i.e. (x-a)^2 touches the x axis at a?

    Thanks

    I'm able to access the file easily. Try right clicking and then choosing "save link as" (it might be something different on a Windows computer).
