What are QuadraticFunctions?
Quadratic functions are a cornerstone concept in A-Level Maths,requiring the use of graphs to analyse the properties and behaviour of thesemathematical equations.
With real-world applications ranging from physics, engineering, andeconomics, understanding quadratic functions is essential for modelling andanalysing real-life scenarios, such as projectile motion or optimising profit.
With the ability to transform quadratic graphs through translations,reflections, and stretches, A-Level students can gain insight into how changingcoefficients and constants affect the shape, position, and orientation of thegraph.
Examining the vertex, axis of symmetry, and x and y-intercepts canhelp students make predictions about the solution of the quadratic equation.
Graphing quadratic functions is a fundamental problem-solving skillthat A-Level Tutoring or a-level-tutoring.net can help UK A-Level students,A-Level teachers, and parents master.

Graphing QuadraticFunctions
When graphing quadratic functions, it is important to accuratelyplot points and identify the vertex, axis of symmetry, and any intercepts. Togain a deeper understanding of quadratic functions, it is essential to analyzeparabolas. One way to do this is by examining the vertex form of a quadraticfunction, which is given by the equation y = a(x - h)2 + k, where(h, k) represents the coordinates of the vertex. To graph a quadratic functionin vertex form, we can use a table to find key points and plot them on a graph.The table can have three columns: x, y, and the value of the function. Bysubstituting different values of x into the equation, we can determine thecorresponding y-values and plot the points. This process allows A-levelstudents to visualize the shape of the quadratic function and accuratelyidentify important features such as the vertex, axis of symmetry, andintercepts.

Solving QuadraticEquations
To help UK A-level students, A-level tutors and parents reachsuccess, it is important to understand the methods for solving quadraticequations. Two common methods used to solve quadratic equations are factoringand using the quadratic formula.
Factoring involves breaking down the quadratic equation into twobinomial factors and setting each factor equal to zero to find the solutions.This method is most effective when the equation can be easily factored.
On the other hand, the quadratic formula can be used to find thesolutions for any quadratic equation. The formula states that the value of xcan be found by substituting the coefficients a, b, and c into the formula andsolving for x. It is important to note that the quadratic formula can bederived by completing the square on the general form of a quadratic equation.
