424 divided by four= 106 the buuble is correct
Let's draw a Venn diagram of the given relation:
The domain is the set of all first elements of ordered pairs (x-coordinates) and the range is the set of all second elements (y -coordinates).
Therefore, from the picture above, the answer is:
Answer:
1. 
2.
and 
Step-by-step explanation:
We have the expression
to find the solutions we have to clear
. Then,
Add 64 in both sides of the equation.

Now we have to re-write the equation:
⇒
Then,

Apply square root on both members

Now substitute back 
1. 
2. 
Solving for x:
1. 
2. 
Then the solutions for
are:

To find the x intercepts of the graph
we have to replace with y=0.
This means: 
We already found the solutions for the expression, but we have to consider only the real solutions.

Because in a graph we can't have imaginary solutions.
Then the x intercepts of the graph are:
and 
The graph of the function is:
Answer:
x = 251/765, y = 698/85, z = 7/3
Answer: functions graphically because they were, after all, just sets of points in the plane. Then in ... However, of these two answers, only x = −2 fits in the domain x < 1 for this piece. This means the only x-intercept for the x < 1 region of the x-axis is (−2,0). ... use the formula f(x) = x − 3, so the point on the graph (1,f(1)) is (1,−2).
