Quasi-derivative
Okay, let's pretend you have a bunch of toys, but you don't know which one to play with first. You ask your mom for help, and she picks one for you to play with. This is what we call a decision-making process.
In math, we also have a way of making decisions called a function. It's like a set of rules that tells us what to do with a number to get another number. For example, if we have a function that says "add 3 to any number," we can use it to find the answer if someone asks us "what's 5 plus 3?" We apply the function by adding 3 to 5, and we get the answer 8.
Now, let's say we have a function that describes how fast something is moving at any given time. We can use that function to find out a lot of things, like how far it will travel in a certain amount of time. But what if we don't have the function? What if all we have is a graph that shows how fast the thing was moving at different times?
This is where the quasi-derivative comes in. It's a way of estimating what the function would look like if we had it. It's like trying to guess what someone would say next, based on what they've already said. We can use the graph to estimate the slope of the function at different points, and that gives us a good idea of what the function would look like. It's not exact, but it's pretty close, especially if the graph is smooth and doesn't have any sudden jumps or changes.
So, the quasi-derivative is a way of estimating what a function would look like if we don't have it, based on a graph that shows how the function is changing over time. It helps us make decisions and understand how things are changing, even if we don't have all the information we need.
