Function graphs are really interesting because they show up in our daily lives! Let’s explore some types of functions and how we see them around us:
Linear functions are super common. They are often shown as ( y = mx + b ).
Think about your phone bill or how much money you make at a job. They usually go up at the same rate all the time. For example, if you make £10 an hour, your total pay after ( x ) hours can be figured out easily.
Quadratic functions look like ( y = ax^2 + bx + c ). You can find these in many areas, especially in physics!
For example, when you throw a ball, it follows a curved path. If you are working on a sports project, knowing about the graph of ( y = x^2 ) can help you guess how high or far the ball will go.
Cubic functions are a bit trickier. They can be written like ( y = ax^3 + bx^2 + cx + d ).
These functions can show things like how a population grows quickly over time. You may also see them in engineering. They help explain how materials might react when they are under pressure.
Exponential functions have the form ( y = a \cdot b^x ) and are everywhere!
You can find them in finance, especially when calculating things like interest on savings. They also help us understand how diseases can spread among people.
Learning about these graphs is not just for tests; it helps us see how math connects to real life! Whether it’s about money or science, function graphs show us ideas that we can relate to every day, making math a little more meaningful!
