what is the vertex form of the quadratic function that has a vertex at (3,4) and goes through the point (4,2)

the answer is a. 72. but i cant answer with less than 20 characters so here's some random text talking about it.

the answer is  

c.

14,469 cubic feet

i know this one is right

0.2cm < 1.5cm : 0.2cm > 1.5cm

erica would now have 20 bottles of water because 26-6=20.

i hope this : )
