Many students find it hard to understand different kinds of functions, which can lead to some common mistakes. Let’s break them down:

1. Linear Functions:

   • Students often mix up the slope and intercepts.
   • They sometimes do not see that the rate of change is constant.

2. Quadratic Functions:

   • It's easy to confuse the vertex with the axis of symmetry.
   • Some students forget how the leading coefficient affects the shape of the graph.

3. Exponential Functions:

   • Students might get confused between growth and decay.
   • They can make errors when changing the graphs.

To get better at these functions, students should try the following:

• Practice drawing and using graphs.
• Make sure they understand the key ideas behind each type of function.
• Solve word problems that show how these functions are used in real life.

With regular practice, students can improve their skills and avoid these common mistakes!
