What is the difference between a linear quadratic and a quadratic quadratic?
There is no quadratic equation that is 'linear'. There are linear equations and quadratic equations. Linear equations are equations in which the degree of the variable is 1, and quadratic equations are those equations in which the degree of the variable is 2.
What is the difference between a linear and quadratic function?
A linear function is a line where a quadratic function is a curve. In general, y=mx+b is linear and y=ax^2+bx+c is quadratic.
What is the difference between linear and quadratic equations?
A linear equation has the form of mx + b, while a quadratic equation's form is ax2+bx+c. Also, a linear equation's graph forms a line, while a quadratic equation's graph forms a parabola.
What mathematical relationship between variables is suggested by a graph showing a half-parabola?
inverse linear or quadratic
What conclusions can you draw if the line of best fitting on a linear graph does not slope either up or down but is horizontal?
The conclusion would be that there is no evidence of a linear relationship between the variables. There could well be a non-linear (eg quadratic) relationship.
What is the Advantages of scatter diagram?
It allows a quick look at the data to establish whether or not there is any relationship between the variables and also an indication of the nature of the relationship: linear, quadratic, power etc.
When there is a curved line on a graph what type of relationship there is between the dependent variable and the independent variable?
Well, it's a non-linear relationship. It could be inverse, or quadratic, or many other things.
What is the difference between a linear equation and an quadratic equation?
A linear equation, when graphed, is always a line. A quadratic is a curve. Also, linear equations are of the form y=mx+b where m and b are arbitrary constants and quadratics are y=(x^2) +mx +b where m and b are arbitrary constants.
What is the difference between linear and non linear scales?
A linear scale is a scale with equal divisions for equal vales, for example a ruler. A non linear scale is where the relationship between the variables is not directly proportional.
What are the characteristics of a curved relationship and how does it differ from a linear relationship?
A curved relationship is characterized by a non-linear pattern where the relationship between two variables does not follow a straight line. This means that as one variable changes, the other variable does not change at a constant rate. In contrast, a linear relationship is characterized by a straight line where the relationship between two variables changes at a constant rate. The main difference between a curved and linear relationship is the shape of the graph that represents the relationship between the variables.
What is A Quadratic Sequence?
A Quadratic Sequence is when the difference between two terms changes each step. However the secondary difference (the difference between each primary difference.) is always the same. E.G. 6 9 14 21 +3 +5 +7 primary difference.(changes) +2 +2 secondary difference(stays the same) this is not a linear sequence in which the primary difference stays the same. another way to visualise this is on a graph. if you plotted a quadratic sequence onto a graph there would be a curve. a linear sequence would be a straight line. hope this helps. Thanks To harisdagr8 for his help.
What are the drawbacks of quadratic regression?
None, really. A hand-held calculator may not perform the necessary calculations but that seems to me the only drawback. But that is less of a problem that trying to force a quadratic relationship between two variables into a linear model!
