Hint to start out the problem:
eg. For f(4), use the first expression, (x-3)^2 because 4 is greater than 1.
The options in the attached images.
Remember that parallel lines are those lines that have equal slopes.
That is, the angle with respect to the horizontal axis is equal.
We observe that we have two pairs of parallel lines.
A vertical pair
A horizontal pair
Answer:
A vertical pair
A horizontal pair

Answer:
78.6km/h
Step-by-step explanation:
<em><u>Speed=distance÷time</u></em>
<u>distance</u>=21km
<u>time</u>=16 minutes<u>(convert into hour by dividing it</u> <u>with 60)</u>
=16÷60=0.267
Speed=21÷0.267=78.65km/h
![speed = \frac{distance }{time}](https://tex.z-dn.net/?f=speed%20%3D%20%20%5Cfrac%7Bdistance%20%7D%7Btime%7D%20)
![speed = \frac{21}{0.267} = 78.6km(h](https://tex.z-dn.net/?f=speed%20%3D%20%20%5Cfrac%7B21%7D%7B0.267%7D%20%20%3D%2078.6km%28h)
