Question 11(a) Use the method of completing the square to evaluate:
i.
ii.
(b) Hence, graph
i.
ii.
y = x2 + 4x + 1
y = x2 + 3x + 3
x2 + 3x + 3 = 0
x2 + 4x + 1 = 0

Question 12
(a) Use the Quadratic Formula to find the x-intercepts of the following
i.
ii.
iii.
(b) Hence, graph them :)
y = − 3x2 − x + 4
y = x2 − 8x + 16
y = − x2 + 4x + 4

The Exponential Curve
The milk & tea conundrumYou’re at home making yourself a nice cup of tea. Just as you’re about to pour the milk into your tea, you get
an important phone call. You want the warmest possible cup of tea so should you put the milk into the tea
before or after the phone call?
Circle one:
Before Phone Call / After Phone
