Answer:
Direction parabola opens upward.
Vertex of parabola is (27,-9).
Axis of symmetry is 
.
Step-by-step explanation:
Note: Option sets are not correct.
The vertex form of a parabola is
...(1)
where, (h,k) is vertex and x=h is the axis of symmetry.
If a<0, then parabola opens downward and if a>0, then parabola opens upward.
The given function is
...(2)
On comparing (1) and (2), we get
, so direction parabola opens upward.
, so vertex of parabola is (27,-9).
So, axis of symmetry is .

Answer:
<u>You can buy 32 pens for £8.</u>
Step-by-step explanation:
12÷3 = 4 ---> which means you get 4 pens for £1.
since you get 4 pens for £1, you need to multiply 4x8 to find how many pens you can buy for £8.
4x8 = 32.
<u>You can buy 32 pens for £8.</u>
