Question 3
There are shapes two knobs cannot reach
Using the same two knobs, bring the error to 3.0 or less.
โpoints = error
0goal 3.0 ↑40
Bring the error to 3.0 or less.
What to take away
Two knobs cannot do it.y = ax + b only ever draws a
straight line, so it cannot make a hill.
Even the best straight line leaves an error of 14.28. No setting of the knobs
gets you to 3.0. Problem 3 exists so that you can confirm it is out of reach. That is the end of it, so
go straight on to Problem 4 below.Add more knobs and you get there.
Where this pays off
You can tell “I am turning them badly” apart from “the shape is not enough”. This one is the shape.
