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.
What is the range of the equation y 4x2 - 8?
y > -8
What is the range of the function y equals -x 2 plus 1?
y < 1
What is the domain of the continuous quadratic function y equals 4x2 plus 2?
The domain is from negative infinity to positive infinity. The range is from positive 2 to positive infinity.
What is the range of the secant function?
absolute value of y> 1

How is the graph of y 4x2 1 different from the graph of y 4x2?
Unfortunately, limitations of the browser used by Answers.com means that we cannot see most symbols. It is therefore impossible to give a proper answer to your question. Assuming the first function is y = 4x2 + 1, and the second y = 4x2 then the first graph is 1 unit higher than the second.
What is the range of the equation y 4x2 - 8?
y > -8
How do you write 4x2 plus y equals 16 using function notation?
First you need to solve for y. So write 4x2+y=16 so y=16-4x2 Now write f(x)=16-4x2
What is the range of the function y equals -x 2 plus 1?
y < 1
What is the domain of the continuous quadratic function y equals 4x2 plus 2?
The domain is from negative infinity to positive infinity. The range is from positive 2 to positive infinity.
What is the range of the secant function?
absolute value of y> 1
What is the range of the function y 2sin x?
y = 2sin(x)? If that's your function, well we know that sin(x) oscillates between y = 1 and y = -1, but in our case we have double that from 2sin(x), so our range is -2 to 2.
Is y equals 4x2-1 a linear equation?
yes
How do you factor 4x2 - y2?
4x2-y2 = (2x-y)(2x+y)
Is 4 x squared opens upward?
We have f(x) = y = 4x2 When x = 1, f(1) = 4(1)2 = 4 and when x = -1, f(-1) = 4(-1)2 = 4 So for negative and positive values of x, y is always positive. So y = 4x2 opens upward. Visit the link mentioned below to know more about the given function.
What is the square root of -4x2?
In real numbers there is no square root of -4x2 However, when using complex numbers where √-1 = i, then: √-4x2 = 2xi If you were asking, for example, with regard to the difference of two squares, eg y2 - 4x2, then you are actually finding the square root of 4x2 which is 2x, giving: y2 - 4x2 = (y + 2x)(y - 2x)
