How do you write a quadratic function whose. - Socratic.org.
Quadratic Equation. The word “quadratic” comes from “quadratum”, the Latin word for square. Hence, we define a quadratic equation as an equation where the variable is of the second degree. Therefore, a quadratic equation is also called an “Equation of degree 2”.

Learners must be able to determine the equation of a function from a given graph. Discuss and explain the characteristics of functions: domain, range, intercepts with the axes, maximum and minimum values, symmetry, etc. Emphasize to learners the importance of examining the equation of a function and anticipating the shape of the graph.
Please note that the Standard Equation of the quadratic function is actually a transformation of the function. Below is its graph. 3. Characteristics of Graphs of Quadratic Functions. The graphs of quadratic functions are so popular that they were given their own name. They are called parabolas. The graph is SMOOTH and symmetric to a line.

Recognizing Characteristics of Parabolas. The graph of a quadratic function is a U-shaped curve called a parabola. One important feature of the graph is that it has an extreme point, called the vertex.If the parabola opens up, the vertex represents the lowest point on the graph, or the minimum value of the quadratic function. If the parabola opens down, the vertex represents the highest point.
Part I: Write the factors (in the form x - a) that are associated with the roots (a) given in the problem. (2 points) Part II: Multiply the 2 factors with complex terms to produce a quadratic expression. (4 points) Part III: Multiply the quadratic expression you just found by the 1 remaining factor to find the resulting cubic polynomial. (4 points).
