### About

A* A-Level Mathematics A* A-Level Further Mathematics Studying pure mathematics at UCL at present. 2015-2016, KT Tuition, Whitehaven. I tutored GCSE & A-level mathematics for a year with this company. I also self-taught myself A-level further Mathematics, so I consider myself to have an insight into what needs to be done in order to achieve a good level of understanding. I am still studying (mathematics at university) so I am constantly in the mindset of teaching myself which Is a mindset I also incorporate into my tuition.

MATHS ðŸ’¯#### F (x)=x^3-7x^2-24x+18 Sketch the graph of the gradient function y=f'(x). Use algebraic methods to determine any points where the graph cuts the coordinate axes and mark these on the graph. Use calculus, find the coordinates of any turning points on the graph. I don't know how to answer this question. Please help!?

Cuts the x-axis at x ={-3, 5+sqrt(19), 5-sqrt(19)} Turning points occur at x={-4/3, 6} Found by setting fâ€™(x)=0 (taking the first derivative and set...
