Domain And Range With Open Circles

Write the domain and range of f using interval notation assuming the problem is in graph form.

Domain and range with open circles. According to the domain and range values we determined 0 0 could not be a part of the range for this function. It is easy to remember which coordinates domain and range refer to because x is alphabetically before y and domain is. Answer by josgarithmetic 34302 show source.

The domain is x l h r x h r the range is y l k r y k r for example if the center is 2 3 and the radius is 5 then the domain is from 3 to. Does that mean that the domain i included in my question is expressed correctly. Answer by edwin mccravy 18315 show source.

Finding the domain and range of a continuous function with an open and closed point. The graph agrees with this conclusion. What is the domain and range if there is a open circle at 5 4 and a closed circle at 5 2.

Endgroup jlee oct 1 14 at 1 20. Begingroup so anytime there is a portion of the graph with open circles it is not included in the domain correct. The domain of a circle is the x coordinate of the center of the circle plus and minus the radius of the circle.

What is the domain and range if there is a closed circle at 4 4 and a open circle at 3 5 thanks write the domain and range of f using interval notation. X 4 and x 4 are not included in the domain because of the open circles at these values. If we find 0 0 the square root function is undetermined at that point and does not appear to exist so we now have evidence that our domain and range are correct.

Write the domain of the graph of the function shown below in interval and inequality notations. Assume the center is h k and the radius is r. Hence the domain in interval notation is written as 4 6.
