There are different types of graphs that show functions in unique ways. Let’s break down four main types:

1. Linear Graphs:

   • These graphs show a steady, constant change.
   • Their equation looks like this: (y = mx + c). Here, (m) is the slope, which tells you how steep the line is.

2. Quadratic Graphs:

   • These graphs represent functions in the form (y = ax^2 + bx + c).
   • They have a U-shape, called a parabola, which shows that the rate of change varies.

3. Exponential Graphs:

   • These graphs represent functions like (y = a \cdot b^x).
   • They show quick growth or decline, meaning they can rise or fall very sharply.

4. Graphs of Trigonometric Functions:

   • These graphs have a repeating wave-like pattern.
   • An example is (y = \sin(x)), which has a cycle that repeats every (2\pi).

Knowing how to read these graphs makes it easier to understand data from the real world.
