How To Find Domain And Range Of A Graph Khan Academy

Welcome to my presentation on domain of a function.

How to find domain and range of a graph khan academy. Khan academy is a 501 c 3 nonprofit organization. This problem has a function drawn on the cartesian coordinate plane. Since no values of x are negative domain is all real numbers.

Then since the vertex is the low point take the primary square root of 4 to get 2 so range is y 2. But the domain of a function is just what values can i put into a function and get a valid output. Determining the domain of a function.

This exercise uses a graph to determine the domain and range of functions. So we re told this h of x right over here and once again we have to figure out whether these x values are in the domain or not. Vertex is at 1 4 and it opens upward.

Let s do one last example. Domain and range from graph our mission is to provide a free world class education to anyone anywhere. So what s is the domain.

So function we can view as something so i put a. Khan academy is a 501 c 3 nonprofit organization. Substitute 1 into the quadratic to get 1 2 2 1 5 1 2 5 4.

The domain of a function you ll often hear it combined with domain and range. Domain and range from graph. Now the range at least the way we ve been thinking about it in this series of videos the range is set of possible outputs of this function.
