Domain And Range Real Numbers

All positive real numbers ос.

Domain and range real numbers. It is the distance from 0 on the number line. Therefore the domain is all real numbers except 3 and 5. For the denominator not to be zero we need to avoid the numbers 3 and 5.

Y y 0 r indicates range. All positive real numbers ob. The same applies to the vertical extent of the graph so the domain and range include all real numbers.

Domain infinity infinity range infinity infinity. F x logs x 2 1 oa. Further 1 divided by any value can never be 0 so the range also will not include 0.

Ir we could also use interval notation to assign our domain and range. The domain and range are all real numbers because at some point the x and y values will be every real number. All of these definitions require the output to be greater than or equal to 0.

1 question what is the domain and range of this function. Example 4 calculate the domain and the range of the function f x 2 x. Putting it all together this statement can be read as the domain is the set of all x such that x is an element of all real numbers the range of f x x 2 in set notation is.
