Question

What is the domain of the function?

all real numbers less than or equal to 4

all real numbers greater than or equal to –3

all real numbers greater than or equal to –1

all real numbers between –3 and 1, inclusive

Answer 1

A good clear graph is given. By identifying the x-values for which this graph exists, we can identify the domain. This graph begins at x = -3 and continues forever as x increases. Thus, the domain of this function is [-3, infinity).
