domain: The set of all points over which a function is defined. range: The set of values the function takes on as output. function: A relationship between two quantities, called the input and the output; for each input, there is exactly one output. The domain and range are the main characters of a function. The domain of a function is the inputs of the given function on the other hand the range signifies the possible outputs we can have. Through this article on the domain of a function, we will aim to learn about the domain meaning in math along with questions to understand how to find Hi, it looks like you're using AdBlock : (. Domain is what goes in,Range is what comes outFor inverse functionsx goes in, and angle comes out.So, domain is all possible values of xand range is all possible values of anglesDomain and Range of Trigonometry FunctionsDomainRangesin-1 [–1, 1] [-π/2,π/2]cos-1 [–1, 1] [0,π]tan-1R (-π/2,π/2 By the strict definition of a function, the question makes no sense, since you haven't defined the function unless you've stated what the domain is up front. But by the convention described above, the domain is the nonzero reals. Look at the example in the video. 1) It tells you the function is called "h (t)". This tells you that the input value is the variable "t". So, your domain will be based upon the values for "t". 2) The problem tells you that "t" is the days from the time she bought the plant. This tells you that "t=0" would be the time she bought the plant. So we can first limit the domain (values of a) to Natural numbers and range (values of b) to Real positive numbers. But that is not enough to find the actual domain as a and b must also satisfy the condition given. However in your case b ∈R+ b ∈ R + so b ∈ (0,∞) b ∈ ( 0, ∞) so for a also a ∈ [0,∞) a ∈ [ 0, ∞) but only Range definition: the extent to which or the limits between which variation is possible. See examples of RANGE used in a sentence. The range of a function f consists of all values f(x) it assumes when x ranges over its domain. Example 1. The range of f(x) = 2 + √x. − 1 is [2, To see that, we observe that the natural domain of this function is [1, since we request that the expression from which we extract the square root is non-negative.

We can observe that the graph extends horizontally from −5 to the right without bound, so the domain is [ − 5, ∞). The vertical extent of the graph is all range values 5 and below, so the range is ( − ∞, 5]. oWSt.
