How to find the range of a function graph

Solution: We can see that the graph extends horizontally from -2 to 3, but the -2 is not included. Therefore, the domain is (-2, 3]. Also, we see that the graph extends vertically from 2 to -2, so the range is [-2, 2]. EXAMPLE 2 The following graph

Find domain and range from graphs

The domain is all x-values or inputs of a function and the range is all y-values or outputs of a function. When looking at a graph, the domain is all the values of the graph from left to right. The range is all the values of the graph

Determine Domain and Range from a Graph

The range here is going to be, we could say f (x) is a member of the real numbers such that f (x) does not equal zero. f (x) does not equal zero. So the domain is all real numbers except for zero, the range is all real numbers except for zero. So the big takeaway here is the

Why clients love us

If you are in middle or high school you need this, but don't like that sound after scane change it, 10 out of 10 highly recommend downloading. The speed and accuracy that problems get solved is amazing, and I love how once you type the equation or problem, you simply tap on it to resubmit it instead of typing it all over again.

James Atkin

So easy to use and explains step by step to find the answer and you could also just scan the problem for fast and easy answers. This is only a suggestion, but with implementing a dark mode, you could save lives. I really enjoy this app it's fast and it is so amazing I can finish all of my math homework whenever you don't have time.

Thomas Roebuck

Great app really easy to use basically no ads and you can even take pictures of your problems and they will answer really quickly so overall a great app. In my opinion,we can learn many methods with this app.

Finding Domain & Range from the Graph of a Continuous

1+y \ge 0 1+y ≥ 0. which means that y \ge -1 y ≥ −1. If we use interval notation, we can write Range (f) = [-1, +\infty) Range(f) = [−1,+∞) . In this example, we could have solved it using the fact that f (x) = x^2 - 4x + 3 f (x) = x2 −4x+3 is a
