Core maths graph question Watch

Question 2 part 2.

How would you draw this?
2. 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.
4. 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
5. So all of us agree
