The domain is all real numbers, and the range is nonnegative real numbers (y ≥ 0).
D = {x [element of reals]}R = {y [element of reals]|y >= 4}
apex what is the range of the absolute... answer is nonnegative real num...
The Domain and Range are both the set of real numbers.
No. The domain is usually the set of Real numbers whereas the range is a subset comprising Real numbers which are either all greater than or equal to a minimum value (or LE a maximum value).
The domain is all real numbers, and the range is nonnegative real numbers (y ≥ 0).
Y = x squared -4x plus 3 is an equation of a function. It is neither called a domain nor a range.
y is greater than 0 x exist in a set of real numbers
The domain is from negative infinity to positive infinity. The range is from positive 2 to positive infinity.
The answer depends on the domain for x. For example, if the domain is x = 7, then the range is 55. If the domain is all Real numbers, then the range is y >= 6.
x2+2x+1=y or y=x2 In this function the domain is x equals real values and the range is y equals all real values provided y is more than or equal to zero.
The domain and range can be the whole of the real numbers, or some subsets of these sets.
D = {x [element of reals]}R = {y [element of reals]|y >= 4}
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, ∞).
The domain of y = 1/x2 is all numbers from -infinity to + infinity except zero. The range is all positive numbers from zero to +infinity, except +infinity.
The domain and the range depends on the context. For example, the domain and the range can be the whole of the complex field. Or I could define the domain as {-2, 1, 5} and then the range would be {0, 3, -21}. When either one of the range and domain is defined, the other is implied.
y = x2 describes a parabolic curve with a focal point at the location 0, 0 and an infinite range greater than or equal to zero.
