what is the domain of this function? all real numbers {x|x≥12} {x|x<3} {x|x>12}
Answer
Answer:
all real numbers
Explanation:
Step1: Recall the definition of domain
The domain of a function is the set of all possible input values (x - values).
Step2: Analyze the graph
For a graph of a function (in this case, a V - shaped graph which is an absolute - value - like graph), there are no restrictions on the x - values. The graph extends infinitely to the left and to the right. So, every real number (x) can be used as an input for this function.
