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: line graph color mix, quantity of blue paint, in mm, on x axis and quantity of red paint, in mm, on y axis. x axis has a scale from 0 to 9 increments of 1. the y axis has a scale of 0 to 18 increments of 2. straight line connecting 3, 2 and 7, 12 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
