Graphs are pictures that help us see the differences between linear and nonlinear functions. But sometimes, understanding them can be tricky.
Challenges:
Curvy Shapes: Nonlinear functions can look really complicated. This makes it hard to tell what kind of function it is just by looking.
Crossing Points: Linear functions usually cross the axes in a clear way, but nonlinear functions can hide that with their twists and turns.
Solutions:
Check the Slope: With linear functions, the slope stays the same. You can find this by looking at different points on the graph to see if the slope doesn't change.
Compare Functions: By plotting several points, you can see how they change. If they go up or down at a steady rate, it’s likely a linear function.
With a little practice, students can get better at understanding these graphs!
