OpenStudy (accessdenied):
The function of square root is not defined on the real plane for negative values. So, our restriction on the domain would be the numbers for which 6x + 12 < 0. 6x + 12 < 0 6x < -12 x < -2 These are the points where h(x) is NOT defined. So, the interval for which our function IS defined (the domain) is everything not in x<-2, or x >= -2. We would graph this on a number line like... |dw:1329369849390:dw|
