Basic functions - practice problems

In mathematics, basic functions are fundamental operations or relationships that map inputs to outputs. The most common types include:

1. Linear functions (e.g., f(x) = mx + b ) graph as straight lines with constant slope.
2. Quadratic functions (e.g., f(x) = ax2 + bx + c ) form parabolas and model acceleration or area.
3. Exponential functions (e.g., f(x) = a^x ) grow/decay rapidly and appear in population or interest calculations.
4. Trigonometric functions (e.g., sin(x), cos(x) ) relate angles to ratios in triangles and model periodic phenomena.
5. Polynomial functions (e.g., f(x) = x3 - 2x ) combine terms with powers and are used in approximations and physics.

These functions form the foundation for advanced mathematical concepts.
