What is the rule for the function x equals 0 1 2 3 4 y equals 8 6 4 2 0?
y = 8 - 2*x
When y equals 1 what is x in the function 5x-8 equals y?
5x - 8 = yWhen y = 1,5x - 8 = 1Add 8 to each side of the equation:5x = 9Divide each side by 5:x = 9/5 = 1.8
How do you know that y is a function of x?
If you plug in y for the x function, and it equals the answer you got, it is right.
What type of function is represented by the equation y equals -2lxl?
y - |x| is an expression, not a function.
A relation where there is only one y-value for every x-value?
A function
Is y equals 8 a function?
Yes.
Why is y equals -8 a function?
y = -8 is a function because when graphed, it passes the vertical line test.
What type of function is y equals 2x plus 8?
Y = 2X + 8 is a linear function of the form, Y = mX + c. A line.
Is 2y equals 8 a linear function?
Yes, 2y = 8 is a linear function. 2y = 8 is the same as y=8/2, or y=4, which is a vertical line.
Is the function y equals 6x plus 8 a proportional relationship?
No.
What is the function rule of y equals 2x if x equals 1 2 3 and 4?
y = 2, 4, 6, 8
What is the rule for the function x equals 0 1 2 3 4 y equals 8 6 4 2 0?
y = 8 - 2*x
When y equals 1 what is x in the function 5x-8 equals y?
5x - 8 = yWhen y = 1,5x - 8 = 1Add 8 to each side of the equation:5x = 9Divide each side by 5:x = 9/5 = 1.8
Is 8y equals 7 plus 3x a function?
yees because if you divide everything by 8 to get y=7/8+3x/8 which is a linear function since it fits the equation y=mx+b
If y equals 8 what does y plus 8 equals?
16. Because if y=8 then the question becomes 8+8. Which equals 16.
What algebraic property is 8 equals x and x equals y?
Transitive property: If 8 equals x and x equals y, then 8 equals y.
What are function and relation?
A function is an equation that gives a unique answer. A relation does not. Example: y = 3x + 1 is a function. If I give you x, you can determine y. And that y is unique to that x. So if x = 1, you know y = 4. No other of x gives y = 4 as an answer. So y = 3x + 1 is a function. Example: y = 4x2. So if I give you x = 1, y = 4. But y = 4 if I also give you x = -1. So y = 4x2 is not a function, it is a relation.
