For example, in the function y = f(x) = 2x y, x is independent and y is dependent (in other words, y is a function of x) The valid values for a given independent variable x are collectively called the "domain" The valid values for a given dependent variable y are collectively called the "range" If a ticket costs 2 dollars, find the domain and range of this Precalculus The function f has a domain of 0,5and a range of 0,3 Start by sketching a potential graph of f Suppose the function k is defined as k(x)=f(x−3) Determine the domain and range of k Domain RangeSine The graph is periodic and repeats every 2Π I think this function should be familiar Domain All real numbers R, also written as (–∞,∞)We can input any real number Range The output from the "sine" function box (I'm sorry, I really do think this way!) is restricted to numbers between –1 and 1, including both endpoints So it is –1,1

Domain and range of f(x) = sin(x) – 5
Domain and range of f(x) = sin(x) – 5-From the pictures above, it is very clear that the range of y = sin x and y = cos x is {y 1 ≤ y ≤ 1} Domain of csc x and sec x We know that sin (k π) = 0, cos (2k1) π /2 = 0, here "k" is an integer Then, k = 2, 1, 0, 1, 2, For k = 2, sin (2 π) = 0 and cos (3 π /2) = 0 For k = 1The domain of a function is any input that won't break it For example, the domain of f ( x) = 1 x − 3 is anything except x = 3 because division by zero is undefined ( − ∞, 3) ∪ ( 3, ∞) The range of a function is its outputs The range of f ( x) = 1 x − 3 is ( − ∞, 0) ∪ ( 0, ∞)

Example, if f(x) = sinx then the range is given by −1 ≤ f(x) ≤ 1 If we have a composed function gf then its range must lie within the range of the second function g Here is an example to show this Take domain is x 6= 0 , range is −2 ≤ y ≤ 2 wwwmathcentreacuk 5 c mathcentre 09Its domain and range can be found from the domain and range of sin(x) The csc( x ) cannot be defined for those values of x for which sin( x ) = 0 Its domain is all real numbers excluding x = 0TAP THE ARROWS BELOW TO ADVANCE f(x)=cos(x) Domain and Range (infinity,infinity) 1,1
Explanation The sine function is repetitive and continuous and bounded between 3 and 3 and so since domain is all possible input x values, these are all real numbers, and since range is all possible output y values, these are all real numbers between 3 and 3, both endpoints included Answer link Let f R R be defined by f(x) = 1 – x Then the range of f is (a) R (b) (1, ∞) (c) (1, ∞)What is domain and range?

The domain of y = sin x is "all values of x", since there are no restrictions on the values for x (Put any number into the "sin" function in your calculator Any number should work, and will give you a final answer between −1 and 1) From the calculator experiment, and from observing the curve, we can see the range is y betweeen −1 and 1We could write this as −1 ≤ y ≤ 1If f is a function from set A to B and (a,b) ∈ f, then f(a) = b b is called the image of a under f and a is called preimage of b under f Summary Domain is defined as the entire set of values possible for independent variables The Range is found after substituting the possible x values to find the yvalues Video Lesson Related Threads on Find the domain and range of this function Find the domain and range of f(x)=10^(sinx)10^(cscx) Domain and range of composite function Last Post
