B

Step-by-step explanation:

The question states that Dimitri payed the same price for all stocks, so they can all be represented as x. The question will be easier to understand if we line up the stock changes in least to greatest order:

- 10.10   - 4.15    - 3.55    + 1.30    + 8.75

    D          A          E            B           C

x is the original price, not one with an increase or decrease, so it is at 0.

- 10.10   - 4.15    - 3.55         x        + 1.30    + 8.75

    D          A          E                           B           C

x is between  - 3.55 and + 1.30, yet 1.30 is closer to 0, so + 1.30 is the closest to x, or the purchase price.

The answer is B, hope this helps :)

guess at question:

a vertical line intersects the graph of g(x,y) = 0 at two points. what conclusion follows about the function f(x) implicitly defined by g(x,f(x)) = 0?

the domain of f(x) cannot include the x coordinate of any such vertical line.

informally, f(x) is not a function, and

g(x,y)=0 cannot be solved for y uniquely.

the relation r = {(x,y) such that g(x,y) = 0} is a function if

for all (a,b) ∊ r and (c,d) ∊ r, a=c implies b=d.
