What do we call the set of all possible values of x in a given function?
Recall from your previous algebra classes that the set of all possible input values for a function is called the domain of the function, and the set of all output values for a function is called the range. Given y = f (x), the x variable is called the independent variable and represents an input value from the domain.
Is all real numbers x except for X where X equals?
The domain of a function is the set of all possible inputs for the function. For example, the domain of f(x)=x² is all real numbers, and the domain of g(x)=1/x is all real numbers except for x=0.
What is the set of all possible values that the variable X can take in a relationship?
A function is a relation (rule) that assigns each element in the domain to exactly one element in the range. The set of all the values which may be input into afunction. That is, the set of all the values the independent variable may assume. Graphically, the domain is the set of all the x-coordinates.
What do you call the X-values or the input?
All of the values that can go into a relation orfunction (input) are called the domain. All of the values that come out of a relation or function (output) are called the range. Domain: all x-values that are to be used (independent values).
Is domain the X or Y?
The domain is the set of x -coordinates, {0,1,2} , and the range is the set of y -coordinates, {7,8,9,10} . Note that the domain elements 1 and 2 are associated with more than one range elements, so this is not a function.
Which relation is not a function?
ANSWER: Sample answer: You can determine whether each element of the domain is paired with exactly one element of the range. For example, if given a graph, you could use the vertical line test; if a vertical line intersects the graph more than once, then the relation that the graph represents is not a function.
What is H in limit?
h is not “one point on the secant line”, it is the horizontal distance between the two points on the secant line. So saying “h goes to 0” means “Let the two points close in on eachother”.
