C) It is an odd function therefore -f(-x) = f(x) For example: f(-2) = -4 ---> ∴ -f(-2) = 4 f(2) = 4 ∴ -f(-2) = f(2) [If f(2) is in the 1st quadrant then-f(-2) will be in the 3rd quadrant) (3,0) ---> x-intercept at x=3 Stationary point at x=1 Gradient is positive for x>1 Gradient is negative...

A) (1,0) and (-3,0) are x-intercepts At x= -1 there is a stationary point, could possibly be a point of inflection The last two lines prove that it is a maximum stationary point • (for x<-1 it is a positive gradient, therefore a positive curve / ) • (for x>-1 it is a negative gradient, therefore...
