Hello from MrBillDoesMath!
Answer:
See Discussion below.
Discussion:
Let's look at the given statements:
1. The domain of the graph is all real numbers
Answer: False as sqrt(x) is only defined for x > =0
2. The range of the graph is all real numbers
Answer: False as the range of f is the set of positive real numbers and 0
3. The domain of the graph is all real numbers less then or equal to 0
Answer: False as the domain of sqrt(x) does NOT include negative numbers (at least for real-valued functions)
4. The range of the graph is all real numbers greater than or equal to 0
Answer: True. By definition the sqrt(x) is the positive square root of x (and 0 as well)
Thank you,
MrB
