Best Answer

Yes, y=x-4 is linear, since the highest power on x is 1 (y = x1-4)

What does non- linear function mean?

It means if you plot the function it is not on a straight line For example y = 3x + 4 is linear function y = x squared is non linear


Is y equals x - 4 a linear function?

Yes, since y changes proportionally with x.


Is y equals -x plus 2 a linear function?

Yes, y=-2+x is a linear function.


Is y x -4 a linear function Yes yx-4 is linear since the highest power on x is 1 (y x1-4)?

Only partly true. the highest power of y also needs to be 1 - which it is.


Is y equals x plus 4 a linear function and why?

Yes. y + x = 4 is a linear function because the highest order (exponent) on any dependent or independent variable is 1. So if it were y^2 + x = 4 or y + x^3 = 4 or yx + 4 = 0 or anything like that, it would be non-linear. If that doesn't help, if you rearrange y + x = 4 into standard y = mx + b format you get y = -x + 4. So it's a straight line with a slope of -1 and y-intercept of 4. Any time you have an equation that just has the letters in it (x, y, z, etc. any letter) without any exponents, it's a linear equation.


Do a linear equation and a function share the same definition?

No. A function need not be linear. For example, y = sin(x) is a function of x but it is not a linear equation.


Is the inverse of a linear function not a function?

The inverse of a linear function is always a linear function. There are a few ways to approach this.To think about it, you can imagine flipping the x and y axes. Essentially this equates to turning the graph of the linear function on its side to reveal the new inverse function which is still a straight line.More rigorously, the linear function y = ax + b has the inverse equation x = (1/a)y - (b/a). This is a linear function in y.


What is nonlinear expression?

It can be thought of as a function that does not graph to a line when plotted. For example, y=4 or y=5x are linear. But y=x2 or y=x1/2 or y=ln(x) are not linear


The equation y-x is a parent linear function. Its parent function is...?

if you need to reflect a 2-d object on a graph over its parent linear function then do as follows: (x,y) --> (-y,-x) hope that helps


What is the parent function for a linear equation?

Y=x


Is there a difference between linear equations and functions?

A linear equation IS a function. A function can look like X2+X+C, or X3+0, or X+Y+C, or many other ways. The function X+Y+C is a function in two variables, and can be a linear equation.


Why are not all functions linear equations?

Linear equations can be written as y = mx + b. Any other function would be non-linear. Some linear equations are: y = 3x y = 2 y = -2x + 4 y = 3/4x - 0.3 Some non-linear functions are: f(x) = x2 y = sqrt(x) f(x) = x3 + x2 - 2
