Visualizing functions can really help you understand differentiation better. Here’s how it works:

1. Getting the Idea of Derivatives:

   • Graphs show us the slope of a function at any point. This slope is linked to its derivative. For example, if you want to find the slope at a certain point $x$, you can use the formula $\frac{f(x + h) - f(x)}{h}$, especially as $h$ becomes very small.

2. Finding Important Points:

   • When you look at graphs, it's easier to spot critical points. These are points where the derivative $f'(x) = 0$ or where it doesn't exist. About 30% of problems need you to identify high and low points just by looking at the graph.

3. Seeing the Effects of Different Rules:

   • Using rules like the Product Rule or Quotient Rule is simpler when you can see them in action. For example, the Product Rule, which looks like $d(uv)/dx = u'v + uv'$, helps show how the slopes of two functions affect their product.

Using visual tools can lead to a deeper understanding of how differentiation changes the behavior of functions. This can make your overall math skills much better!
