Question

Please please please help me!

Dylan created color panels for a wall using a mix of only green and blue paints. He plotted the quantities of blue and green 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, the X axis and Quantity of Green Paint, in mm, the Y axis. X axis has a scale from 0 to 10 increments of 1. Y axis has a scale of 0 to 20 increments of 2. Straight line 1, 2 and 9, 14 is drawn

Which statement best describes the domain of the function represented in the graph?


0 ≤ x ≤ 9 or x is between 0 and 9, inclusive
2 ≤ x ≤ 14 or x is between 2 and 14, inclusive
1 ≤ x ≤ 9 or x is between 1 and 9, inclusive
1 ≤ x ≤ 14 or x is between 1 and 14, inclusive

Answer 1

The answer is the 3rd one

Answer 2

The correct option is 3.

Explanation:

It is given that the quantities of blue and green paints used for each mix and connected them using a line segment, as shown in the graph below:

The line have two end points A(1,2) and B(9,14).

Domain is the set of inputs. In a graph all the values of x for which the graph is defined, are domain of the function.

The line is defined from x=1 to x=9. So, the domain of the function lies between 1 to 9 (inclusive).

`1\leq x\leq 9`

Therefore, option 3 is correct.
