Suppose there is a simple index of three stocks, stock X, stock Y, and stock Z. Stock X opens the day with 5000 shares at $4.30 per share. Stock Y opens the day with 2000 shares at $3.20 per share. Stock Z opens the day with 8000 shares at $4.90 per share. This simple index rises 4.9% over the course of the day. What is the value of the index at the end of the day? Round your answer to the nearest hundred

1. d.90

2. e. none of these (80)

3. a. 0

4. b. 6

5. e. none of these (10)

6. a. 5

(1, –1), (16, –4), (36, –6)

step-by-step explanation:

given that the function is

this can also be written as

we have to graph this function and check which list of points lie on the graph

see attachment for graph:

we find that the points lying are (1,-1) (16,-4) and (36,-6)

since square root is there we find that x can only be posiitve but y can be since square root both positive and negative.
