- 2 makes this zero and provides the vertical asymptote. So,
from - infinity to - 2 and from - 2 to positive infinity
Give the domain for
The domain is from negative infinity to positive infinity. The range is from positive 2 to positive infinity.
It depends on the domain but, if the domain is the real numbers, so is the range.
It is a quadratic function which represents a parabola.
Assuming the domain and range are both the real numbers (or rationals): Yes, it is 1 to 1 Yes, it is onto and the inverse is x = (y-3)/4
Give the domain for
If the domain is the real numbers then so is the range.
Assuming the domain and codomain are properly defined, then YES.
Y = x squared -4x plus 3 is an equation of a function. It is neither called a domain nor a range.
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.
The domain is from negative infinity to positive infinity. The range is from positive 2 to positive infinity.
The domain of the function f (x) = square root of (x - 2) plus 4 is Domain [2, ∞)
The function is a simple linear function and so its nature does not limit the domain or range in any way. So the domain and range can be the whole of the real numbers. If the domain is a proper subset of that then the range must be defined accordingly. Similarly, if the range is known then the appropriate domain needs to be defined.
The answer depends on the domain. If the domain is the whole of the real numbers, the range in y ≥ 1. However, you can choose to have the domain as [1, 2] in which case the range will be [2, 5]. If you choose another domain you will get another range.
