Answer:
96 km/hr
Step-by-step explanation:
Divide the distance traveled by the time it took to get the rate:
288 / 3 = 96
we can use properties of functions to find this out
for 
if b is even, then the ends of the function go in the same directions (both up or both down)
if b is odd, then the ends of the function go in different directions (one up and one down)
if a is positive and b is even, then both ends point up
if a is positve and b is odd, then it goes from bottom left to top right
if a is negative and b is even, then both ends point down
if a is negative and b is odd, then it goes from top left to bottom right
given 
a=5>0
b=4 which is even
so it has both ends pointing up
bottom right graph is yo answer
8w
-8w times -w is like -8*-1 which would just make the number positive.
