Let's see what's the domain and range for the given function ~
![\qquad \tt \dashrightarrow \:domain \in [ -5 , 4 ]](https://tex.z-dn.net/?f=%5Cqquad%20%5Ctt%20%5Cdashrightarrow%20%5C%3Adomain%20%5Cin%20%5B%20-5%20%2C%204%20%5D%20)
or
Because domain = all values of x between its maximum (4) and minimum (-5) value [ including them ]
![\qquad \tt \dashrightarrow \:range \in[ -4 , 9 ]](https://tex.z-dn.net/?f=%5Cqquad%20%5Ctt%20%5Cdashrightarrow%20%5C%3Arange%20%5Cin%5B%20-4%20%2C%209%20%5D)
or
Because range = all values of y between its maximum (9) and minimum (-4) value [ including them ]

Answer:
Return trip travel time: 7h
Step-by-step explanation:
Let d be the distance.
Index 1 refers to initial trip, index 2 refers to the return trip.
v1=70mi/h
v2=40mi/h
t2=t1+3h, or t1=t2-3h (travel times)
d=v1×t1=v2×t2
v1×(t2-3)=v2×t2
v1 t2 -3 v1=v2 t2
v1 t2 - v2 t2=3 v1
t2(v1-v2)=3v1
t2=3v1/(v1-v2)
Or
t2=3×70/(70-40)=3×70/30=7h
