Quadratic graphs produce a characteristic U-shape (parabola) and are tested at both foundation and higher tier. Students must plot quadratics from tables, identify key features like turning points and roots, and use graphs to solve equations.
Our tutors see these errors again and again. Knowing them in advance gives you a head start.
Joining plotted points with straight lines instead of a smooth curve
Making sign errors when substituting negative x-values into the equation
Forgetting that the parabola opens downward when the coefficient of x squared is negative
This topic is tested by the following exam boards. Our tutors are specialists in each one.
Quadratic equations appear throughout the higher tier GCSE paper and are a significant step up from linear equations. Students need to factorise, complete the square, and use the quadratic formula to find solutions.
AlgebraStraight-line graphs are tested at every tier and form the basis for understanding gradients, intercepts and real-world modelling. Students need to plot lines from equations, find gradients and interpret y = mx + c.
AlgebraFunction notation is a higher-tier topic that formalises the input-output relationship. Students evaluate, combine, and find inverses of functions, building skills that are directly extended at A-Level.
