Alright, 
directix is y=something so it opens down or up
we use
(x-h)²=4p(y-k)
the vertex is (h,k) 
and p is distance from focus to vertex
if focus is above directix, p is positive
if focus is below directix, p is negative
so we gts
focus=(1,1)
directix is y=-1
1>-1
focus is above
oh, vertex is in middle of focus and directix
so
beteeen (1,1) and y=-1 is, hmm
that is a distance of 2 vertically
2/2=1
1 down from (1,1) is (1,0)
vertex is (1,0)
p=1
so
(x-1)²=4(1)(y-0)
solving for y to get into f(x)=something form
(x-1)²=4y
y=1/4(x-1)²
f(x)=1/4(x-1)²

Answer:
50,000 miles
Step-by-step explanation:
First,
If C is the annual operating cost, you can modify/substitute into the equation,
21,100 = 0.37m + 2600
Second, solve the equation for m,
0.37m = 18,500
m = 50,000
