What is the function table for x equals 3?
First column, of x values, is the domain of x - whatever that may be. Second column, of function values is always 3.
How do you Complete function table using the equation yx 4?
well you have to look at the table if it says yx 4 then you have to use any number in the 'x"column and multiply it by the number on the "y"column then add four and check out the difference... do the same with another number and if you have the same difference then is correct.!!! :D
How do you determine if a function is even?
A function f(x) is Even, if f(x) = f(-x) Odd, if f(x) = -f(-x)
How would you determine the slope of a linear function from a table?
slope = change in y values divided by change in x values. m = (y2-y1)/ (x2-x1) pick 2 ordered pairs from the table and use the formula above.
What is some advantages when you see a rule function rather than listing function values on a table?
When you see the actual function (e.g. f(x) = ...) you can know what each input corresponds to, and can construct any table. If you are given just the table, you cannot always predict the function correctly, since the function the table seems to represent does not necessarily have to be that function. For example, it might seem that x : f(x) -2 -4 -1 -2 0 0 1 2 2 4 would correspond to f(x) = 2x, but this is not necessarily the case. There could be some arbitrary function that just happens to contain those five points.
What is the function table for x equals 3?

How do you graph a function in trigonometry?
y = sin x, or y = cos x etc. can be graphed by making a table of values. The x column in the table would be angle measurements (usually in degrees or radians) and the y column would be the trig. function value. Then plot the points and sketch the curve going thru those points. Ex: for y = sin x x , y 0 0 30 0.5 45 0.707 etc and then graph these

How do you create a table of values for each rule with at least four values for x?
For each rule draw a table with 5 rows and 2 columns. At the top of each table write a caption denoting which rule applies to that particular table. In the top row of each table write the letter "X" in the first column and the letter "Y" in the second column. Now for each table in the first column in rows 2,3,4, and 5 write the values of X that apply to the experiment. Now apply the rule for each value of X for a particular table (particular rule) and write the value of Y (obtained by observation or calculation) in the corresponding column
How do you determine if a function is even?
A function f(x) is Even, if f(x) = f(-x) Odd, if f(x) = -f(-x)
How do you write ordered pairs from a function table?
The function table will have two columns, one for the x-value and one for the y-value. Form ordered pairs (x,y) by inserting the values from one row of the table.
How can you complete a table for the equation y equals x-22?
You can't "complete" it, because there are an infinite number of (x, y) pairs that could be included in the table. The best you can do is: -- Decide how many lines you want in the table. -- Pick that many different numbers, and list them in the 'x' column of the table. -- For each number, subtract 22 from it and write the result next to it in the 'y' column.
How would you determine the slope of a linear function from a table?
slope = change in y values divided by change in x values. m = (y2-y1)/ (x2-x1) pick 2 ordered pairs from the table and use the formula above.
How do you graph a function without a table?
Suppose you have a function f, of a variable X. You select a value for X, say x. Calculate the value of f(x) that is, the value of the function when X takes that value x. Then, instead of writing the result in a table, mark the point [x, f(x)] on the coordinate plane. Repeat with other values for X and join up the points.
Domain and range of a function?
The domain of a function determines what values of x you can plug into it whereas the range of a function determines the values that are your results. Therefore, look at the y-axis if you want to determine the range of a function and look at the x-axis if you want to determine the domain.
What is The test to determine if a graph is a function is?
A graph is represents a function if for every value x, there is at most one value of y = f(x).
Y-values decrease as the x-values increase how is it shown on a table and a graph?
If the table consists of a column of x values and a column of y values, and if the x values are in increasing order, ten the y values will be in decreasing order. The graph of y against x will have a downward slope. That is, the line or curve will be going from top left of the chart to bottom right.
