What are linear and nonlinear regression?
A linear equation is an equation that in math. It is a line. Liner equations have no X2. An example of a linear equation is x-2 A linear equation also equals y=mx+b. It has a slope and a y-intercept. A non-linear equation is also an equation in math. It can have and x2 and it is not a line. An example is y=x2+3x+4 Non linear equations can be quadratics, absolute value or expodentail equations.
Is y equals x2 plus 4 a linear equation?
It is linear in y, quadratic in x. Generally, that would be considered a quadratic.
Is y x2 7 OR y x'squared' 7 a linear equation?
no..
Is y equals 3x a linear equation?
Yes, because non-linear equations involve x2.
What are the roots of the equation x2-6x plus 5?
You don't have an equation there.

Is y equals x2 a nonlinear equation?
If you mean y = x2, then yes, it is nonlinear.
Is y equals x2 plus 4 a linear equation?
It is linear in y, quadratic in x. Generally, that would be considered a quadratic.
What do you mean by linearity in parameter and linearity in model?
Any model can be linear/nonlinear. Linearity can be in parameters or in variables. In Y=a+ b*x1 + c*x2 + d*x3 the model is linear in both parameters (b,c,d) and variables(x1,x2,x3) In Y=a+ (b+c)x1 + c*x2 + d*x3 the model is nonlinear in parameters (b,c,d) and linear in variables(x1,x2,x3) In Y=a+ bx1 + c*x2*x3 + d*x3 the model is linear in parameters (b,c,d) and nonlinear in variables(x1,x2,x3) In Y=a+ bx1 + c*x2*x3 + exp(b+d)*x3 the model is nonlinear in parameters (b,c,d) and nonlinear in variables(x1,x2,x3)
Can an equation be linear if there is a variable on the bottom?
x2
Why can't a nonlinear equation have a value of one?
They can. y = x2 is non-linear (graph it and you'll see that it's not a line, but a parabola). When x = 1, y = 1. So, they can have values of one.
Is y equals x2 plus 2 a linear equation?
No, y=x^2 + 2 is a quadratic equation. A linear equation is one in the form y=mx+b. A quadratic has a form y=ax^2+bx+c.
Is this equation a quadriatic equation 3x³ plus 2x equals -3?
no only equations with x2 and lower powers can be considered quadratic. those with x3 cannot be considered quadratic, just as x2 cannot be considered linear
How do you figure out if an equation is a linear equation?
An equation is linear if the highest power of the unknown in the equation is 1for example an equation with just a variable to the power one such as x, y and so on is linear but one with x2, y2 and above is not linear
Is y x2 7 OR y x'squared' 7 a linear equation?
no..
Is y equals 3x a linear equation?
Yes, because non-linear equations involve x2.
How can the degree of the equation tell us if the equation is linear or not?
A linear equation always has a degree of one because the slope has to be constant to form a line. So, x + 7 is linear, 7 - x is linear, 4x - 3.7 is linear, but anything with x2 , etc. is not linear.
