Domain And Range With Open Circles

Answer by edwin mccravy 18315 show source.

Domain and range with open circles. Begingroup so anytime there is a portion of the graph with open circles it is not included in the domain correct. The range of a circle is the y coordinate of the center of the circle plus and minus the radius of the circle. It depends on two things the radius and the center. Solution to example 5 the graph starts at values of x 4 and ends at values of x 4.

Assume the center is h k and the radius is r. Answer by josgarithmetic 34302 show source. Finding the domain and range of a continuous function with an open and closed point. Hence the domain in interval notation is written as 4 6.

The domain of a circle is the x coordinate of the center of the circle plus and minus the radius of the circle. Write the domain of the graph of the function shown below in interval and inequality notations. X 4 and x 4 are not included in the domain because of the open circles at these values. According to the domain and range values we determined 0 0 could not be a part of the range for this function.

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.
