The interquartile range is used as a measure of variability to overcome what difficulty of the range?
the range influences the extreme
What is the range of the tangent function?
The range is infinite in both directions.
What is the domain and range of the square root of x?
sqrt(x) Domain: {0,infinity) Range: {0,infinity) *note: the domain and range include the point zero.
What is the domain and range of y equals the square root of four minus x squared?
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.
What is the range of the function y equals x2 plus 1?
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.
