What does domain and estimate the range mean in math?
"Domain" means for what numbers the function is defined (the "input" to the function). For example, "x + 3" is defined for any value of "x", whereas "square root of x" is defined for non-negative "x". "Range" refers to the corresponding values calculated by the function - the "output" of the function. If you write a function as y = (some function of x), for example y = square root of x, then the domain is all possible values that "x" can have, whereas the range is all the possible values that "y" can have.
Does the graph x-y2 equals 1 represent x as a function of y?
X - Y^2 = 1 - Y^2 = - X + 1 Y^2 = X - 1 Y = (+/-) sqrt(X - 1) now, X is represented as a function of Y. Function values are generally Y values.
Which the function's values become very positive or negative numbers?
The positive regions of a function are those intervals where the function is above the x-axis. It is where the y-values are positive (not zero). The negative regions of a function are those intervals where the function is below the x-axis. It is where the y-values are negative (not zero).
How you solve equation y is a function of x?
To make y a function x, simply get the y to equal the rest of the values. eg. y=3x+1
Example of quadratic function?
x2+2x+1=y or y=x2 In this function the domain is x equals real values and the range is y equals all real values provided y is more than or equal to zero.
What are the possible values of x called in a function?
The allowable values of x are called the "domain", and the resultant set of possible y values are called the "range".
How do you tell if its relation between range and domain?
Domain is what you can plug into the function (possible x values for y=f(x) type functions) and range is the possible values you can get out (possible y values).
Is x equals y a function?
y = x This is a line and a function. Function values are y values.
What is the domain of the function y equals 2x plus 3?
The domain of a function is the set of it's possible x values that will make the function work and output y values. In this case, it would be all the real numbers.
What are possible values for y called?
They comprise the codomain or range.
What does domain and estimate the range mean in math?

"Range" refers to the corresponding values calculated by the function - the "output" of the function.

What are the possible values for y called?
The question is somewhat ambiguous, but I would guess that the answer is the RANGE.
Domain of function?
The domain of a function encompasses all of the possible inputs of that function. On a Cartesian graph, this would be the x axis. For example, the function y = 2x has a domain of all values of x. The function y = x/2x has a domain of all values except zero, because 2 times zero is zero, which makes the function unsolvable.
What is the slope of the linear function shown in the graph?
The difference in y-values divided by the difference in x-values. It's called rise over run.
Does the graph x-y2 equals 1 represent x as a function of y?
X - Y^2 = 1 - Y^2 = - X + 1 Y^2 = X - 1 Y = (+/-) sqrt(X - 1) now, X is represented as a function of Y. Function values are generally Y values.
Can the range repeat in a function?
The range in a function is the y values, and yes it can repeat
Does y equals x plus 4 rpresent a function?
Yes it does, Remember Y values are generally function values. So, putting a value into this function, substitution a integer for X, fives you the Y value. Y = X + 4 ( make X 2 ) Y = (2) + 4 Y = So, when X = 2, Y = 6. The function.
