Keira created color panels for a wall using a mix of only red and blue paints. She plotted the quantities of red and blue paints used for each mix and connected them using a line segment as shown in the graph below.

Which statement best describes the domain of the function represented in the graph?
3 ≤ x ≤ 12 or x is between 3 and 12, inclusive
3 ≤ x ≤ 7 or x is between 3 and 7, inclusive
2 ≤ x ≤ 12 or x is between 2 and 12, inclusive
2 ≤ x ≤ 7 or x is between 2 and 7, inclusive

@Yahoo!  can u help ?

agent0smith · Answer

Domain is again all the valid x values. The graph goes from x = 3 to x = 7, so what does that make the domain?

anonymous · Answer

idk :( its not my strongest subject.

agent0smith · Answer

Well if the graph goes from x=3 to x=7, then the domain has to be$$3\le x \le 7$$

agent0smith · Answer

Since x is valid between 3 and 7

anonymous · Answer

so it would be 2 ≤ x ≤ 7 or x is between 2 and 7, inclusive ?

agent0smith · Answer

No it's the second option, 3 ≤ x ≤ 7 or x is between 3 and 7, inclusive

anonymous · Answer

that was my second guess lol thank u :)

agent0smith · Answer

No prob :)
