To get their combined time, get the sum of Vega's time and Janice's

Therefore, their combined time for their part of the relay is 53.659 seconds.
First, let's find g(4). After we find it, we can substitute the value into
.
To find g(4), we need to substitute x = 4 into the function
, as shown below:



Now that we have found g(4) = 9, we can substitute this value in for
in
.



f(g(4)) is equal to 28.
