Domain graph x 3. Hence for a function f defined by its graph the implied domain of f is the set of all the real values x along the x axis for which there is a point on the given graph. Find the domain and range f x log of x 3 set the argument in greater than to find where the expression is defined. When looking at a graph the domain is all the values of the graph from left to right.

Means that x can be every number smaller than 5. 3 x 8 means that x can be every number greater than or equal to 3 but smaller than or equal to 8. The same applies to the vertical extent of the graph so the domain and range include all real numbers.

Because the domain refers to the set of possible input values the domain of a graph consists of all the input values shown on the x axis the range is the set of possible output values which are shown on the y axis keep in mind that if the graph continues beyond the portion of the graph we can see the domain and. All real numbers or oo oo the domain of any graph includes all the x values that are solutions. Free functions domain calculator find functions domain step by step this website uses cookies to ensure you get the best experience.

X lies between or is equal to 3 and 8 2 x 0 means that x can be every number greater than or equal to 2 but smaller than 0. The function is defined for only positive real numbers. As an example there are points on the graph below at x 3 2 5 2 0 5 2 5 3 3 2 4.

Look below to see them all. For the cubic function f x x 3 the domain is all real numbers because the horizontal extent of the graph is the whole real number line. Graph the function on a coordinate plane remember that when no base is shown the base is understood to be 10.

The range accounts for all y values that are solutions. All real numbers or oo oo range. Means that x can be every number greater than or equal to 7.
