What is the domain of the function shown in the graph?

(infinite, infinite)

Step-by-step explanation

The function doesn't intersect with either of the axis and it doesn't have any points plotted. The arrows used means its infinite.

For this case we have the following function:

 f(w) = 1.1w

 The first thing we must do for this case is to define the variables.
 We have then:
 w: represents watts
 
 We observe that the function varies directly, therefore, we have a linear function and the constant of variation is positive.
 That is, the slope of the line is positive.
 Therefore, the linear function grows.

 
 B) light intensity increases linearly
