Graphs common mistakes

Common mistakes

• Graph transformations common mistake 1

  Writing a final answer without showing the method that justifies it. This can weaken answers for: [Higher only] Sketch translations and reflections of a given function..

  Fix itShow the method first, then give the final answer in the required form. Apply this directly to Graph transformations.

• Real-context and non-standard graphs common mistake 1

  Writing a final answer without showing the method that justifies it. This can weaken answers for: [Foundation and Higher] Plot and interpret graphs, including non-standard graphs in real contexts, to find approximate solutions..

  Fix itShow the method first, then give the final answer in the required form. Apply this directly to Real-context and non-standard graphs.

• Real-context and non-standard graphs common mistake 1

  Writing a final answer without showing the method that justifies it. This can weaken answers for: [Foundation and Higher] Apply graph interpretation to contexts such as distance, speed and acceleration..

  Fix itShow the method first, then give the final answer in the required form. Apply this directly to Real-context and non-standard graphs.

• Real-context and non-standard graphs common mistake 1

  Writing a final answer without showing the method that justifies it. This can weaken answers for: [Higher only] Include reciprocal and exponential graphs in real-context graph problems..

  Fix itShow the method first, then give the final answer in the required form. Apply this directly to Real-context and non-standard graphs.

• Gradients and areas under graphs common mistake 1

  Writing a final answer without showing the method that justifies it. This can weaken answers for: [Higher only] Calculate or estimate gradients of graphs and areas under graphs, including non-linear graphs..

  Fix itShow the method first, then give the final answer in the required form. Apply this directly to Gradients and areas under graphs.

• Gradients and areas under graphs common mistake 1

  Writing a final answer without showing the method that justifies it. This can weaken answers for: [Higher only] Interpret gradients and areas in contexts such as distance-time, velocity-time and financial graphs..

  Fix itShow the method first, then give the final answer in the required form. Apply this directly to Gradients and areas under graphs.

• Circle equation and tangent common mistake 1

  Writing a final answer without showing the method that justifies it. This can weaken answers for: [Higher only] Recognise and use the equation of a circle with centre at the origin..

  Fix itShow the method first, then give the final answer in the required form. Apply this directly to Circle equation and tangent.

• Circle equation and tangent common mistake 1

  Writing a final answer without showing the method that justifies it. This can weaken answers for: [Higher only] Find the equation of a tangent to a circle at a given point..

  Fix itShow the method first, then give the final answer in the required form. Apply this directly to Circle equation and tangent.
