Answer:
The function with the largest value will be
Step-by-step explanation:
we know that
As x increases beyond 25 , that means
x> 25
so
Assume x=30
Substitute the value of x in each equation and find the value of the function, and then compare the results
case 1)
For x=30
case 2)
For x=30
case 3)
For x=30
case 4)
For x=30
therefore
The function with the largest value will be
If it takes 3 hours at 30 km per hour than that 90 km total distance and at 45 km per hour that would mean that distance would be travelled in 2 hours. So the answer should be 2 hours
