# This is frustating- find P watch

1. How the flap do you find P?

Two days before my C3 exam, I realise I can't solve these seemingly basic problems. fml
2. Kick it.

Or give us the question.

Edit: aha, you have conveniently inserted a diagram making me look like an arse. Oh well.
3. P is the point where the two lines 2 - (x + 1) and 2 + (x+1) meet. Another way to think about it is that it's the point where the modulus sign doesn't matter - when does that happen? There's a geometric argument too.

Hmm, actually, I don't know.

Draw yourself a graph of y = |x|. There's one point that obviously doesn't fit in with the rest. Find the odd one out... (alternatively, it's the one that looks like P on your graph!)

Considering f(x)
The max value of f(x) occurs when the modulus component is a minimum
What is the min value the modulus function can take?
Hence what is the maximum value of f(x)?
At what value of x does this occur?
