What S The Domain Of Y X
In this case there is no real number that makes the expression undefined.
What s the domain of y x. The range is the set of all valid values. Even though they are represented differently the above are the same function and the domain of the function is x 2 3 5 6 8 and the range is y 4 8 2 9 3 this is how you can defined the domain and range for discrete functions. Pi 2 y pi 2 this video might help. This website uses cookies to ensure you get the best experience on our website.
In this case there is no real number that makes the expression undefined. Set builder notation for any integer find the magnitude of the trig term by taking the absolute value of the coefficient. The domain is all values of that make the expression defined. If you go to this very useful web site click trigonometry inverse trigonometric functions y arcsin x.
Free math problem solver answers your algebra geometry trigonometry calculus and statistics homework questions with step by step explanations just like a math tutor. The range is the set of all valid values. Use the graph. When we define a function we state to types of variable the dependent variable and the independent variable if we have a function of the form here x is the independent variable and y is the dependent variable that is y depends on x.
Enter link description here but a function must have a one to one mapping and this does not so hence we must truncate the graph so that it has a one to one mapping. Free math problem solver answers your algebra geometry trigonometry calculus and statistics homework questions with step by step explanations just like a math tutor. Use the graph. The original sine function defined for any real argument does not have an inverse function because it does not establish a one to one correspondence between its domain and a range.
The lower bound of the range for secant is found by substituting the negative. The domain of the expression is all real numbers except where the expression is undefined. The following is a fragment from my lecture about y arcsin x presented on unizor com. Domain of a function as the possible values of x.
