The Function F(x)=60x Computes the Number of Minutes in $( f \circ g ) ( \mathrm { x } )$

question 80

Multiple Choice

The function f(x) =60x computes the number of minutes in x hours. The function g(x) =24x computes the
number of hours in x days. What is $( f \circ g ) ( \mathrm { x } )$ and what does it compute?

• A) \(( f \circ g ) ( x )\) =84x ; It computes the number of minutes plus the number of days in x days.
• B) \(( f \circ g ) ( x )\) =1440x ; It computes the number of minutes in x days.
• C) \(( f \circ g ) ( x )\) =1440x ; It computes the number of days in x minutes.
• D) \(( f \circ g ) ( x )\)=1440x² ; It computes the number of minutes in x days.
