What is the domain of a discrete function?
The domain is the possible values that can be input into the function and produce a real number output.
What is the domain and range of y equals x?
The domain of a function represents the set of x values and the range represents the set of y values. Since y=x, the domain is the same as the range. In this case, they both are the set of all real numbers.
Y equals -5xwhat is the domain and range show in graph?
Domain measures X values. Since X isn't restricted by square roots or in the denominator the domain is all real numbers. Range measures Y values. Since X can be anything Y can be anything.
Would the domain be something other than all real numbers provide an example?
It could be a subset: for example, for the function y = log(x), the domain is x > 0. There are many functions whose domain is the complex plane.
Are bounded domain functions periodic?
No. You can always "cheat" to prove this by simply giving the function's domain a bound.Ex: f: [0,1] --> RI simply defined the function to have a bounded domain from 0 to 1 mapping to the codomain of the set of real numbers. The function itself can be almost anything, periodic or not.Another way to "cheat" is to simply recognize that all functions having a domain of R are bounded functions, by definition, in the complex plane, C.(Technically, you would say a non-compact Hermitian symmetric space has a bounded domain in a complex vector space.) Obviously, those functions include non-periodic functions as well.
Are there points of discontinuity for exponential functions?
There are no points of discontinuity for exponential functions since the domain of the general exponential function consists of all real values!
How do you determine the domain and range of relations and functions?
Some functions are only defined for certain values of the argument. For example, the the logarithm is defined for positive values. The inverse function is defined for all non-zero numbers. Sometimes the range determines the domain. If you are restricted to the real numbers, then the domain of the square root function must be the non-negative real numbers. In this way, there are definitional domains and ranges. You can then chose any subset of the definitional domain to be your domain, and the images of all the values in the domain will be the range.
Which parent functions has a domain and range of all real numbers excluding the origin?
y = 1/x
How are domain and range used in the real world?
Domain and range are used when you deal with functions - so basically you use them whenever you deal with functions.
What are the domain and range of the quadratic parent function?
The domain is all real numbers, and the range is nonnegative real numbers (y ≥ 0).
What is the domain of a discrete function?
The domain is the possible values that can be input into the function and produce a real number output.
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.
What is not a characteristic of an exponential parent function?
Periodicity is not a characteristic.
What is the domain and range of y equals x?
The domain of a function represents the set of x values and the range represents the set of y values. Since y=x, the domain is the same as the range. In this case, they both are the set of all real numbers.
Which fundamental functions have all real numbers as the domain?
The domains of polynomial, cosine, sine and exponential functions all contain the entire real number line. The domain of a rational function does not, since its denominator has zeros, and neither does the domain of a tangent function. (1/2)x = true (8/3)x = true
How are a reasonable domain and range determined for a function?
By having some knowledge about the functions involved. The natural domain is the domain for which the function is defined. For example (assuming you want to work with real numbers): The square root of x is only defined for values of x greater or equal to zero. The corresponding range can also be zero or more. The sine function is defined for all real numbers. The values the function can take (the range), however, are only values between -1 and 1. A rational function (a polynomial divided by another polynomial) is defined for all values, except those where the denominator is zero. Determining the range is a bit more complicated here.
What is the domain of the function y equals 2x plus 3?
The domain of a function is the set of it's possible x values that will make the function work and output y values. In this case, it would be all the real numbers.
