This equation is in vertex form so finding the vertex is easy.
Vertex: (-1,4)
Once you find the vertex, axis of symmetry is easy.
x=-1
Then find y intercept by finding h(0).
h(0)=(0+1)^2-4=-3
Now find x intercepts by solving for x when h(x)=0.
(x+1)^2-4=0
(x+1)^2=4
x+1=±2
x=±2-1
x=1,-3

Answer:
$33
Step-by-step explanation:
First we calculate the cost of the overdrafts:
3 overdrafts * $35 = $105
Then, if he maintains an average monthly balance of $600, we can calculate = $600*12 months = $7200 (average yearly balance). And the bank pays him 1% interest per annum:
$7200 * 1% = $72 (this is what the bank pays the graduate per year)
So if the bank charges him $105 and pays him $72, then the net annual cost is = $105-$72= $33
