Find the sum of all distinct integers in the domain of: f(x)=√(196-9x^2)?
Posted on Mar 09, 2008 under domain news and reports |Find the sum of all distinct integers in the domain of:
f(x)=√(196-9x^2)
That's square root (one ninety six minus nine times x squred).
I'm so confused. Please help!

(196-9x^2)=0
9x^2=196
x^2=21.77
x between -4 and 4.
Sum -4+-3+-2+-1+0+1+2+3+4=0
