Okay kiddo, concavification might sound like a big and scary word, but it's not as complicated as it sounds!
Imagine you have a straight line that goes up and down like a rollercoaster. Now, if you take the middle part of that line and push it down, so it becomes a little cave-like shape, that's what we call concavification.
Why would we do this? Well, sometimes we want to make a graph or a chart that looks like a bowl or a valley. We can do this by changing the shape of the line, and that's where concavification comes in!
When we concavify something, we change the curve of the line to make it go downward like a valley or upward like a hill. This can be really useful when we want to show how something changes over time or how different things relate to each other.
So, there you have it, sweetheart! Concavification is just a fancy word for changing the shape of a line to make it look like a valley or a hill. It's a handy tool for making graphs and charts that help us understand how things change or relate to each other.
