X2 plus 3x plus 2 over x plus 2 Identify any restricted values on the domain?
Yorokobifai
The restricted value in the domain is x=-2 because if x were equal to -2, the denominator would be 0 and the expression would become undefined.

How do you determine the range of a function?
Find the maximum and minimum values that the function can take over all the values in the domain for the input. The range is the maximum minus the minimum.
Why is the range the output and the domain the input?
A function may be defined over only certain values. That is, it may have only a certain set of values that can serve as input. For example, in elementary mathematics, the principal square root is only defined for non-negative real numbers. This is the "area" over which the function is valid and so it is called the domain. The mathematical term for the set of output values is actually the co-domain, but many people refer to it as the range.

What is the function of range?
The range is a measure of the difference between the maximum and minimum values that a variable can take, or that a function can take over the relevant domain.
X2 plus 3x plus 2 over x plus 2 Identify any restricted values on the domain. steps please?
(x2+ 3x + 2) / (x + 2) = (x + 1)(x + 2) / (x + 2) = x + 1; but with the following important proviso: (x + 2) can not equal zero; otherwise we are dividing by zero. Thus, (x2+ 3x + 2) / (x + 2) = x + 1, if x ≠ -2; and (x2+ 3x + 2) / (x + 2) is undefined, if x = -2.
Identify the problems of a restricted budget?
over spending is a restricted budget also running out of cash is also one
Is it possible for a polynomial function of degree 3 to have no real zeros?
Yes - but only if the domain is restricted. Normally the domain is the whole of the real numbers and over that domain it must have at least one real zero.
Advantages of frequency domain over time domain?
advantage is that if we represent a composite signal in frequency domain........then we clearly see that how much signals are involved in composite signal and their separate peak values

What is the range when y equals three over x with a restricted domain of 0.5 to 4?
The range is (3/4 to 3/0.5) or 0.75 to 6

What is the difference between relational tuple calculus and domain calculus?
Relational tuple calculus has its variables range over tuples, where domain relational calculus ranges its variables over the field values, or domain elements. Both types of calculus are subsets of first order logic.
What are some advantages of a dot plot over a frequency polygon?
Dotplot allow you to identify original values
What equation is true for some values of its variable and is not true for others?
No equation can have that property. It cannot be an equation if it is not true. If necessary, the domain must be amended. An equation can have different forms over different parts of its domain.

The range is a measure of the difference between the maximum and minimum values that a variable can take, or that a function can take over the relevant domain.
