I don't even know where to start with the first step.1. Write down the range of values of x for which the graph of y = f(x) has a negative gradient.
They're talking about a tangent line, yes? So where do I draw it?2. The equation f(x) + x – 1 = 0 can be solved by drawing a line on the grid.
(i) Write down the equation of this line. 
(ii) How many solutions are there for f(x) + x – 1 = 0?
