Answer 1

(i) = Y intercept-(0,0) , X intercept-(0,0) and (2,0)
(ii) = Horizontal (y= -1)

Vertical (x= -2) and (x=1)

Question 2

Answer 2

(iii) = There are no Critical points
(iv) = Decreasing on (-∞,-2)U(-2,1)U(1,∞)

=No intervals of increase

Answer 3

(v) Inflection points= X=0/(0,0)

Intervals of Concave up on= (-2,0)U(1,∞)

Intervals of Concave down on = (-∞,-2)U(0,1
