The graph shows that x never becomes < 0. In other words the point (-1,0) is not part of the graph. So D is your only answer.
Answer:
Option D is correct.
Step-by-step explanation:
Given: A graph.
We know that The domain of a function is the complete set of possible values of the independent variable.
From given graph x is independent variable.
Generally Domain for the Square root function is all non negative real numbers.
So, from given graph and general domain.
Domain of given graph = x ≥ 0
Therefore, Option D is correct.

Answer:
- See explanation below: either 0.984 cm or 0.85 cm depending on the complete question.
Explanation:
The question is incomplete and, thus, ambiguos.
There are two plausible interpretations: either each side of the prism has a leght of 4.92 cm, or the the units of the given measured is not cm but cm³ and 4.92 is the volume of the prism.
Considering the first option:
The best side length is the first decimal number that divides exactly 4.92cm
- That is 4.92/5 = 0.984 cm
Considering the second option
The correct question would be "If you fill a 4.92 cm³ prism with cubes who’s sides lengths are less than 1 cm what size would be the best"
The best size of the sides lentgths is one that occupies the greatest part of each length.
Assume the prism is a cube. Then, the legth of each side is:
The greatest decimal number that divides 1.70 exactly is:
- 1.70cm/2 = 0.85cm
