Question: 7. (a) (i) Express y = - x ^ 2 - 7x - 15 in the form y = - (x + p) ^ 2

7.

(a) (i) Express y = - x ^ 2 - 7x - 15 in the form y = - (x + p) ^ 2 + q

(ii) Hence, sketch the graph of y = - x ^ 2 - 7x - 15

(b)

(i) Express y = x ^ 2 - 3x + 4 in the form y = (x - p) ^ 2 + q

(ii) Hence, sketch the graph of y = x ^ 2 - 3x + 4
