X2 plus 3x plus 2 over x plus 2 Identify any restricted values on the domain. steps please?
Yorokobifai
(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.

X2 plus 3x plus 2 over x plus 2 Identify any restricted values on the domain?
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 identify the domain and range?
Domain is a set in which the given function is valid and range is the set of all the values the function takes
Y equals -5xwhat is the domain and range show in graph?
Domain measures X values. Since X isn't restricted by square roots or in the denominator the domain is all real numbers. Range measures Y values. Since X can be anything Y can be anything.
What is domain in mathematics?
domain = x-values range = y-values for which x or y is a solution
How can you find the domain and range of a function?
The domain is a subset of the values for which the function is defined. The range is the set of values that the function takes as the argument of the function takes all the values in the domain.

How do you determine the domain and range of relations and functions?
Some functions are only defined for certain values of the argument. For example, the the logarithm is defined for positive values. The inverse function is defined for all non-zero numbers. Sometimes the range determines the domain. If you are restricted to the real numbers, then the domain of the square root function must be the non-negative real numbers. In this way, there are definitional domains and ranges. You can then chose any subset of the definitional domain to be your domain, and the images of all the values in the domain will be the range.
What is domain in mathematics?
domain = x-values range = y-values for which x or y is a solution
How can you find the domain and range of a function?
The domain is a subset of the values for which the function is defined. The range is the set of values that the function takes as the argument of the function takes all the values in the domain.
What are the domain and range of the function?
The domain of a function is the set of values for which the function is defined.The range is the set of possible results which you can get for the function.
What is the difference between domain and range in math?
Domain is the spectrum of values on the x-axis. Domain will be which x-values can be plugged into that equation and give an answer. Range is the same thing, but y-values. On the graph it will be the y-values that are included in the graph.
What is practical domain and range?
Domain: All Possible "x" values Range: All possible "y" values
How do you describe the domain and range of a function?
The domain is the set of values of the input while the range is the set of output values.
How do you identify the roots of a function algebra 1?
If the function of the variable x, is f(x) then the roots are all the values of x (in the relevant domain) for which f(x) = 0.
How do you graph range and domain?
You do not graph range and domain: you can determine the range and domain of a graph. The domain is the set of all the x-values and the range is is the set of all the y-values that are used in the graph.
