r x
–4 –1 0

p
(a) Given p is an integer where –2 , p , 2, state the
value of p. [1 mark]
q
(b) Using the value of p from (a), find the value of q.
Hence, state the axis of symmetry. [2 marks]
(c) Is the quadratic function will change if the graph
Answer:
is reflected in the x-axis? If it changes, gives the
answer in the form of f(x) = ax + bx + c.
