State whether or not each equation or situation represents direct variation. Match each function with the point that represents the vertex of its graph. No one point be used more than once.

1. y = ( x - 3)( x - 7)
(1, 4)
2. y = -2( x + 2) 2
(2, 0)
3. y = x 2 - 2 x - 3
(-5, 4)
4. y = ( x - 2) 2
(5, -4)
5. y = -2 x 2 + 4 x + 2
(1, -4)
6. y = -4( x + 5) 2 + 4
(-2, 0)

b. f(x) = –√x + 3this is the correct answer

it is definatly the 3rd one. very much looks like it, for a good chance, the third one would be best for you.

8(4)^8=72^feet to say that the total can conclude to 8(4) which as you know would mean 8 x 4. that equals 32w. 32^ could make a 72 answer as well. but your coefficent will remain w so your answer is 72w.
