Igot a for both questions. can i get confirmation?

 No. You reversed the domain and range

              #2) B) x ≥ 0

              #3) B) [0, ∞)

Step-by-step explanation:

#2 is asking about the domain, which is all of the x-values.

The graph appears to be touching the y-axis so it equals 0 and all other x-values are greater than zero. (0, 1), (1, 0), (2, -0.8), (3, -1.5), etc.  All of the x-values are moving toward the right, which is positive infinity.      --> x ≥ 0

#3 is asking for the range, which is all of the y-values.

The vertex is at (0, 0) and all other y-values are above zero (positive numbers), moving toward positive infinity.  --> [0, ∞)
