What is the rate of change, or derivative, of the marble’s speed? This derivative is what we call “acceleration.”

Roll the marble down an incline and see how fast in gains speed.

How fast does the marble change location? What is the rate of change, or derivative, of the marble’s movement? This derivative is what we call “speed.”.

Now imagine that the rolling marble is tracing a line on a graph – you use derivatives to measure the instantaneous changes at any point on that line. You are rolling a marble on a table, and you measure both how far it moves each time and how fast it moves. Remember, a derivative is a measure of how fast something is changing. The easiest example is based on speed, which offers a lot of different derivatives that we see every day. Remember real-life examples of derivatives if you are still struggling to understand. For example, in y = 2 x + 4, This is called Leibniz's notation. In a function, every input has exactly one output. Functions are rules for how numbers relate to one another, and mathematicians use them to make graphs. Remember that functions are relationships between two numbers, and are used to map real-world relationships.
