The domain of a function is just all the x-values that have a corresponding y-value. Typically, you need to check for discontinuities or vertical asymptotes. For example, any x value that causes the denominator of a fraction to be 0 must be excluded from the domain, since you can't divide by 0.
A simple case would be f(x) = 1 / x
If x = 0 , the denominator is 0 and the function is undefined; all other values of x have a corresponding value for f(x), so the domain would be x < 0 and x > 0, or (-∞, 0) U (0, ∞).

What are common terms to represent domain and range and how do you find them?
x = the domain y = the co-domain and range is the output or something e_e
How do you find the domain and range of a parabola?
The domain is any subset of the real numbers that you choose, The range is the set of all values that the points in the domain are mapped to.
How do you find the domain and range of f of x equals x squared minus 3x minus 10?
The domain is what you choose it to be. You could, for example, choose the domain to be [3, 6.5] If the domain is the real numbers, the range is [-12.25, ∞).
How do you find the domain?
The domain of a function, is the range of input values which will give you a real answer.For example the domain of x+1 would be all real numbers as any number plus 1 will be another real numberThe domain of x0.5 would be all positive numbers as the answer to square root of a negative number is not realNote:x0.5 means the square root of x* * * * *Not quite. A function is a one-to-one or many-to-one mapping from a set S to a set T (which need not be a different set). A function can be one whose domain is all the cars parked in a street and the range is the second character of their registration number.A mathematical function can have the complex field as its domain and range, so a real answer is not a necessary requirement for a function.
Find the domain and range of the equation 3x - 2y equals 6?
domain is set of real numbers range is set of real numbers
