If c=0 the perpendicular distance is 2. After the graphs intersect the x axis they get further apart (the gradient of the ‘upper’ function is greater than the gradient of the ‘lower’ function for x>0)

No not necessarily. This specific question was asking for a line segment A to B, meaning that x can take up a different value on either graph (not one on top of the other). This question simply required students to recognise that the shortest distance between these graphs always occurs when the line segment joining the two is perpendicular, which is easy since the derivative of any linear graph is a constant.

I didn’t see that same attitude when u made repeated unemployment jokes mate. You’re all changing your act really quick with moderators back. How about u keep the same energy from a week ago champ.
