Graphs are super helpful for understanding limits in pre-calculus! Let me break it down for you:
Seeing is Believing: When we look at a graph, it’s easier to see how a function behaves as it gets close to a certain point. For instance, if a graph shows a function getting closer and closer to a particular y-value while x moves towards a specific value, that helps us understand what a limit is.
Up and Down: By watching how the graph goes up or down, we can guess what the limit might be. Take the example of the function . As x gets closer to 0, the graph goes up towards infinity from the right side and down towards negative infinity from the left side.
Real-Life Examples: Graphs can show real-world scenarios, like how speed changes over time. This helps us better understand limits when we look at things like the fastest speeds or other similar situations.
In short, graphs make the idea of limits easier to grasp and more interesting!
