The relation is not a function. In order for a relation to be a function, the x-inputs of all ordered pairs must not repeat, and if they do, they must have only one output. In this problem, however, (9,4) and (9,1) both have different outputs (y-values). Therefore, there is no function present.

Answer:

C. x = -1 ; x ~8.1

Step-by-step explanation:

First we graph f(x)= -\sqrt{x+2} -3

Here we have x+2 under the square root. x+2>=0, x>=-2

So we take some x  values greater than -2  and find out f(x)  to make a table for graphing

x        f(x)

-2       -\sqrt{-2+2} -3=-3

-1        -4

2        -5

Graph it  and extent the graph

Now we graph g(x)= -2|x-3| + 4

Given equation is in the form of g(x) = a|x-h| + k

where (h,k) is the vertex

here h= 3  and k = 4, so vertex is (3,4)

Now make a table, pick some numbers for x  less than and greater than vertex

x     y

-1     -2|-1-3| + 4=-4

0    -2|0-3| + 4=-2

3    4

6     -2

Both graphs are attached below

The graph of f(x)  and g(x) interests  at x= -1  and x=8.1
