Function Has Domain

Grade 10 answers set 1.

Function has domain. F x frac x 2 81 x 9. The domain of a function is the set of all possible inputs for the function. If one extends the definition of to the piecewise.

The codomain is similar to a range with one big difference. So the domain for this f in particular so the domain for this one if i want to say its domain i could say look it s going to be the set of these curly brackets. The set of possible y values is called the range.

For example the function defined by has no value for thus the set of all real numbers cannot be its domain in cases like this the function is either defined on or the gap is plugged by defining explicitly. If the function has a minimum value that is when a 0 y leq k if the function has a maximum value that is when a 0 download functions worksheets. For domain we have to find where the x value starts and where the x value ends i e the part of x axis where f x is defined.

View answer write the domain in interval notation. The domain of a function on a graph is the set of all possible values of x on the x axis. A codomain can contain every possible output not just those that actually appear.

The range is the set of y values that are output for the domain. The domain of a function is the set of numbers that can go into a given function. The domain of a function a domain of a function is the set of all inputs inputs over which the function is defined over which the function is defined or the function has defined outputs over which the function has defined outputs.

In other words it is the set of x values that you can put into any given equation. The domain is the set of x values that can be put into a function in other words it s the set of all possible values of the independent variable. A well defined function must map every element of its domain to an element of its codomain.
