Addition: Two cars of A and B are driving at a uniform speed on one road. In order to determine the location of the car, we use the axis OX to indicate the road, the original point O as the zero road signs (pictured), and the following agreement: ① speed speed V> 0, indicates that the car is driving towards the positive direction of the axis; speed C <0, indicating that the car is driving towards the negative direction of the axis; speed v = 0, indicating the coordinate S> 0 of the car position on the axis, indicating that the car is located in zero zero The right side of the kilometer label; the coordinate S <0 on the axis position on the axis indicates that the car is located on the left side of the 0 kilometer road; In accordance with the above agreement, the two cars are driving on the highway at a constant speed in the form of a function image in the same corner coordinate system, as shown in the figure. Please answer the following questions: (1) Just the two functional images of the two functional images at a time. The two cars reflected in this highway are filled in the following form. The size of the driving direction speed (KM) H before departure (2) Can two cars meet the two cars? The moment when you meet and the position on the road; if you can't meet, please explain the reason.

1 This question is the 2001 Hebei junior high school test questions I will answer the answer with the test benchmark.

Analysis: (1) See the picture to draw conclusions;
(2) Known the function analysis formula of the two vehicles, and the line of the column section requires T, and the value of S can be available.
Answer: Solution: (1) A car: the negative direction of the X -axis (to the left), 190 kilometers on the right side of the 0 kilometer road mark;
Car B: The positive direction of the X -axis (right), 80 kilometers on the left side of the 0,000 -meter label.
The location of the driving direction speed (KM/H) before departure
Car A 40,000 kilometers on the right is 190 kilometers right on the right side
By Bolt B to the left of the 50,000 -kilometer road on the left 80 kilometers on the left
(2) The two cars meet.
After the Two -hour encounter after T hours,
Available
So after 3 hours of encounter, the encounter was 70 kilometers on the right side of the zero -kilometer road.

This question examines the ability to obtain information from the image by examining the application of a function.

2 The three consecutive even numbers are 18, 20, and 22.
