## Introduction

Students typically take Secondary Math 2, a mathematics course, in their sophomore year of high school. The course builds upon the concepts learned in Secondary Math 1 and introduces new topics such as trigonometry and calculus. Secondary Math 2 is essential for students planning to pursue a career in mathematics or a related field.

A quadratic function is a function of the form f(x) = ax^2 + bx + c, where a, b, and c are real numbers, and x is a real variable. The graph of a quadratic function is a parabola. The term “quadratic” comes from the Latin word quadrants, which means “square.”

An answer key is an important tool for students to use when studying for exams. It allows them to check their work and see what they got right and what they got wrong. This way they can focus their studying on the areas they need to work on the most.

### Quadratic Functions

A quadratic function is a mathematical function that describes a relationship between two variables. The most common type of quadratic function is the parabola. The axis of symmetry divides a U-shaped curve, known as a parabola, in a symmetrical manner. We can express the equation of a parabola as y = ax^2 + bx + c, where a, b, and c are real numbers and x is a variable. This form is what we use to represent a quadratic function.

### A quadratic function can be written in standard form as:

y = ax^2 + bx + c

where a, b, and c are real numbers and a ≠ 0. The standard form of a quadratic function is useful when solving problems, as it can be easily transformed into other forms. For example, the standard form can be used to find the axis of symmetry and the vertex of the function.
