Graphical calculator MODULUSWatch
y= l x^2 l + 3 + l x l i.e the modulus.
i'm using casio fx 9750 G plus. it should be the same for every calc...
|x| = abs(x)
Just checked my 9850, don't know if it's the same, but on mine it's OPTN then pick NUM from the menu at the bottom, then Abs is the first on the left.
can u use a 9850 in the p2 exam??
