    The minus sign would reflect f(x) along the x axis so the line would dip downwards. The "2" would cause the line to be steeper.

    I welcome confirmation from other posters.

    You're right. Another way of saying steeper is stretching along the y axis.

    the graph would be reflected in the x axis and stretched parallel to the y axis by a scale factor of 2 i.e. multiply all the y coordinates by 2 after reflecting
