Quizplus · Accepted Answer

The correct function is $f(x) \cdot g(x)$ because $f(x)$ represents the percentage of students with laptops, and $g(x)$ represents the total number of students. Multiplying these gives the number of students with laptops.

Provide an Appropriate Response (f∘g)(x)( f \circ g ) ( x )(f∘g)(x)
