HI,

You entered g(x)=-l2-x-2.l3-1/2xll+3. Instead of the traditional notation for absolute value, |x|, we use abs(x). Also, if you want to refer to one-half of x, you need to use parentheses: (1/2)x or (1/2)*x.

I can't quite decipher your function because there are three vertical lines, |||, but there needs to be an even number so they can be paired off.

Give it another try, and if you still have a problem, write back.
