Y is the output of x, which is the input. So y= x + 2, y is the result of x + 2. Y is the dependent variable, and x is the independent constant.

Find the rule for each function table?
Well, look for a continuing pattern. Once you find one that makes sense for each value, write it into an equation....look at example below x- 2,4,6,8 y- 4,16,36,64 the rule for this function is y=x squared.
What is a function rule?
how you get x to equal y. it is usually in a graph
What is a rule that assigns exactly one output value to each input value?
A function is a rule which assigns exactly one output f(x) to every input x.
What is the function rule if X is -3 2 4 4.5 and Y is 8 3 1 5?
The rule, using a polynomial function of the lowest order is Un = (12n3 - 36n2 - 145n + 413)/25
How 26 do you write 26 as a product in 2 different ways?
Remember in multiplication that A x B is the same as B x A? Well using this rule we can write that 13 x 2 = 26 and 2 x 13 = 26.
Write an equation for the function describe by this rule the value of y is 10 times greater than the value of x.?
10y = x ======
Write a function rule to calcuate the cost of buying bananas at 39 cents a pound?
f(x)=.39x
How do you write a function rule in algebra?
A function is any rule to assign a value (for example) to a variable "y", depending on the value of variable "x". Such a rule can be written in different ways; in algebra, it is common to write some equation, preferably one that is already solved for "y", such as: y = x2 + 3

How do you write an equation that shows y is a function of x?
The normal way of showing that y is a function of x is to write y = f(x).
What is an example of an algebraic rule that is not a function?
x2 - y2 = (x + y)(x - y) is an identity, not a function.
For each function determine whether y varies directly with x if so find the constant of variation and write the function rule x 2 3 5 y 14 21 35?
Yes, and the constant is 7.
Which function rule describes the number of centimeters y as a function of a number of millimeters x?
y = x/10
For each function determine whether y varies directly with x if so find the constant of variation and write the function rule x 2 y 14?
You need more than one pair of values in order to answer the question.
Write the rule in algebraic form?
you write it like this (x,y) ----> (-x+4, y-5)
What is a function rule?
how you get x to equal y. it is usually in a graph
What does function rule mean in math?
The rule of a function in math is what relates the input value to the output value. For example, if f(x) = x2, the "function rule" is to square the input value to get the output value.
