The light intensity of a certain brand of light bulb is modeled by the function f(w) = 1.1w where w represents watts. which statement best describes the function? a) light intensity increases exponentially b) light intensity increases linearly c) light intensity is constant d) light intensity increases

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
