The **graph** of is a parabola. The **graph** looks like if a > 0 if a < 0 The maximum or minimum point on the **graph** is called the vertex. The x-coordinate of the vertex is: The y-intercept; the y-coordinate of the point where the **graph** intersects the y-axis. Example 1: 4x - 12x 2. Given any **quadratic** expression, first, check for common factors, i.e. 4x and 12x 2. We can observe that 4x is a common factor. Let’s take that common factor from the **quadratic** expression. 4x - 12x 2 = 4x (1 - 3x) Thus, by simplifying the **quadratic** expression, we get the expression, 4x - 12x 2.

A **quadratic** functionis a function that can be written in the form of f x a x h )2 + k (a ≠ 0). In a **quadratic** function, the variable is always squared. The table shows the linear and **quadratic** parent functions. Notice that the **graph** of the parent function f(x) = x2 is a U-shaped curve called a parabola. **Quadratic** Equations A term like x2 is called a square in algebra because it is the area of a square with side x The adjective **quadratic** comes from the Latin word quadratum for square. So a **quadratic** equation is one in which the highest index number of a term with x in is x2 Examples of **quadratic** equations: y = x2 y = x2 + 1 y = x2 + 3x - 10.
