Find the domain of the following functions. Write the answer in interval notationNote: If the answer includes more than one interval write the intervals separated by the "union" symbol, U. If needed enter ox as Inf and -∞ as -Int
When using interval notation in WeBWorK,rememberthat:You use 'I' for and '-I' for .And use 'U' for the union symbol.a) The range of prices so that demand is elastic isb) The range of prices so that demand is inelastic isa) The unit price necessary for unitary elasticity is 扫码...
In interval notation a logically equivalent statement does not use the word or, but rather a symbol for what is called the union of two groups of numbers. The symbol for union coincidentally looks like a U, the first letter of union. ...

The Greek symbol μ is pronounced “mew,” and the notation E[X] denotes the expected value of the random variable X. The summation sign Σ means that we add up the products XiP[Xi]. Suppose, for example, that X is equal to the number of heads that occur when three coins are flippe...
