  1. For the red graphcall the function f(x) What is f(3) ? Tolka Derivator NOTE: There are no ”curves” here. It is just an example. Think of distance as THE DISTANCE FROM THE STARTING POINT. If I walk from here to ICA and back, for example, the distancewould be zero.

  2. For the red graphcall the function f(x) What is f(3) ? f(3) is 6. Whatdoes this actuallymean? Tolka Derivator NOTE: There are no ”curves” here. It is just an example.

  3. For the red graphcall the function f(x) What is f(3) ? f(3) is 6. Whatdoes this actuallymean? It means that the car has travelled 6 metres after 3 seconds. Tolka Derivator NOTE: There are no ”curves” here. It is just an example.

  4. For the red graphcall the function f(x) What is f(3) ? f(3) is 6. Whatdoes this actuallymean? It means that the car has travelled 6 metres after 3 seconds. What is f’(3)? Tolka Derivator NOTE: There are no ”curves” here. It is just an example.

  5. For the red graphcall the function f(x) What is f(3) ? f(3) is 6. Whatdoes this actuallymean? It means that the car has travelled 6 metres after 3 seconds. What is f’(3)? What is the ”lutning” at this point? It is 2 of course. Whatdoes this mean? The distance is increasing at A RATE OF 2 metres per second. This is, of course, the velocity. (Hastigheten). Tolka Derivator NOTE: There are no ”curves” here. It is just an example.

  6. For the red graphcall the function f(x) What is f’(5) ? f’(5) is 0. Whatdoes this actuallymean? It means that the car has stopped. What is f’(8)? Tolka Derivator NOTE: There are no ”curves” here. It is just an example.

  7. What is f’(8)? What is the ”lutning” at this point? It is -8/3. Whatdoes this mean? The car is going ’backwards’. It is returning to where it came from. When time = 10, distance = 0 so we are back wherewestarted from. Tolka Derivator NOTE: There are no ”curves” here. It is just an example.

  8. IMPORTANT In the exam you willprobably be asked to EXPLAIN what f(x) and f’(x) actually MEAN. The answer to f’(x) ALWAYS has to refer to a rate, such as ”an increase of 5 metres in 1 second.” Key word: hastigheten. Tolka Derivator NOTE: There are no ”curves” here. It is just an example.
