Math Clip Art--Applications of Linear Functions: Distance vs. Time 07

Topic

Linear Functions

Description

This math clip art image continues the series on applications of linear functions, focusing on the domain and range of the distance-time function. The image emphasizes that the domain of this function is x ≥ 0, and the range is y ≥ 0. This representation helps students understand the practical constraints on the variables in real-world applications of linear functions.

By explicitly stating the domain and range, this image bridges the gap between abstract mathematical concepts and their real-world implications. It illustrates that in the context of distance and time, negative values don't make practical sense. This approach helps students grasp the importance of considering real-world constraints when working with mathematical models, enhancing their ability to apply linear functions to practical situations.

Teacher's Script: "Let's think about what makes sense in our car journey. Can time be negative? Can distance be negative? Of course not! That's why we say the domain – all possible x values – is x ≥ 0. Time starts at zero and goes forward. Similarly, the range – all possible y values – is y ≥ 0. The car's distance starts at zero and increases. This is how math connects to reality. When you're solving real-world problems, always consider: Do all values make sense in the real world? This thinking will help you use math more effectively in everyday situations."
