sqrt(12 x+24) a square root function becomes undefined if the quantity under the root is zero. i.e. sqrt(0)=undefined. So that is your only restriction; you have to find what values of x will make the quantity under the root zero. 12x+24=0 > x=2 So, all numbers other than 2 can be plugged in for x. infinity < 2 < +infinity is the range
