Q:
# 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

Accepted Solution

A:

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.

Answer:

B) light intensity increases linearly

f(w) = 1.1w

Therefore, the linear function grows.

Answer:

B) light intensity increases linearly
