Test your understanding of multiple roots, graphing, inequalities, and applications.
Its question set has not been written, so there is nothing here to attempt. Nothing you have done is lost, and the lessons either side of it are unaffected.
To test yourself on this material now, use the module quiz, which covers the same content.
1. State the multiplicity of each root of $P(x)=(x-1)^3(x+2)^2(x-4)$. (2 marks)
2. Describe the end behaviour of $y=-3x^4+2x^3-x+5$. (2 marks)
3. Solve $(x-1)(x+2)(x-3)\ge0$. (3 marks)
4. A box with square base has height equal to twice the side of the base. If the volume is 250 cm³, find the dimensions. (3 marks)
