Use the graph.
What is the domain of y x. Domain x as for all real values of x y is defined but it is given that x 0 so domain is 0. Y 3 when attempting to find the domain and range it is best if you actually draw the diagram so you don t miss any points and when you are unsure. It is also. X 3 0 the function is undefined.
The domain is all values of that make the expression defined. The denominator of y cannot be zero as this would make y undefined. But looking at the equation 2 x 1 2 3 we can tell that it is an upside down parabola shifted to the left by 1 and down by 3. The range is the set of all valid values.
Solve x 1 0rarrx 1larrcolor red excluded value domain is x in oo 1 uu 1 oo to find range rearrange. Oo 2sqrt 11 7 uu 2sqrt 11 7 oo the domain is all values of y where y is a defined function. The domain of the expression is all real numbers except where the expression is undefined. X as x is defined for only.
Therefore at x 3 the function is undefined. The range of an even indexed radical starts at its starting point and extends to infinity. If the denominator is equal to 0 the function is typically undefined. So the domain is stated as oo 3 uu 3 oo.
But in this case since square root is in denominator it can t be equal to zero. If you don t know what the graph looks like just plot a bunch of points. In this case there is no real number that makes the expression undefined. The domain is all values of that make the expression defined.
Equating the denominator to zero and solving gives the value that x cannot be. The given function is y x as domain is that values of x for which y exists and range is those values of y for which x exists. Its vertex will 1. The lower bound of the range for secant is found by substituting the negative.
