A continuación, se coloca el cociente que se obtenga (9) . Y luego el número obtenido (49) se multiplica por dicho cociente (9). Después, se resta (441) a la cantidad operable (492) del radicando. El cociente obtenido (9) es la segunda cifra de la raíz, quedando (29) Bajamos el siguiente par de cifras y repetimos los pasos anteriores.

It's a good thing that the domain is confined or the graph is. That function is undefined if x < - 3
At exactly x = - 3, f(x) = 0 and that's your starting point.
So look what happens to this graph. If x = 0, f(0) = y = 3. So we are starting to see that as x get's larger so does f(x). The graph tells us that x = 0 is bigger than x = - 3.
Let's keep on plugging things in.
As x increases to 5, f(5) = 5. x = 5 is larger than x = 0, and f(5) > 3.
One more and then we'll start drawing conclusions. If x = 9 then f(9) = y = 6.
x = 9 is larger than x = 5. f(9) = 6 is just larger than f(5) which is 5
OK I think we should be ready to look at answers. There's nothing there that makes the answer anything but a. Let's find out what the problem is with the rest of the choices.
B
The problem with B is that as x increases, f(x) does not decrease. We didn't find one example of that. So B is wrong.
C
C has exactly the same problem as B.
D
The second statement in D is incorrect. As x increases f(x) never decreases. No example showed that.
The answer is A <<<< Answer.

Step-by-step explanation:
The domain is a list of all possible x-values, this graph starts at 0 and proceeds to positive infinity, making the domain:
[0,∞)
The range is a list of all possible y-values, this graph starts at -1 and proceeds to positive infinity, making the range:
[-1,∞)
x-intercepts Are where the line crosses the x-axis, in this graph the line only crosses the x-axis at x of 2. Making its only x-intercept 2.
y-intercepts Are where the line crosses the y-axis, in this graph the line only crosses the y-axis at y of -1. Therefore its y-intercept is -1.
In function notation when a question asks for f(x) its asking for the y values at the given x-values. At x of 3 the y value equals 1.
