So here goes, I am given on a grid the drawing of the graph y = xsquared - 2x -4

1 - I am asked to write down the coordinates of the minimum point of the curve - **THIS I CAN DO, NO HELP NEEDED**

2 - Use the graph to find estimates of the solutions to the equation xsquared - 2x - 4 = 0. Give your answer to 1d.p. **THIS I CAN DO, NO HELP NEED**

3 - Draw a suitable straight line on the grid to find estimates of the solutions of the equation xsquared - 3x - 6 = 0 **THIS I CANNOT DO, AS IT IS A QUADRATIC AND THEREFORE WOULD PRODUCE A BELL SHAPE CURVE AND NOT A STRAIGHT LINE AS THEY SAY, NEED HELP PLEASE**

4 - For y = xsquared - 2x - 4

4a) Find dy/dx **CAN DO THIS, NO HELP NEEDED**

4b) find the gradient of the curve at the point where x = 6 **NEED HELP WITH THIS PLEASE**

Many thanks in advance,

Nat
