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.
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.
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.
a linear relationship is characterized by the form y=mx+b and a quadratic relationship is characterized by the form y=x^2+bx+c. Graphically represented, a linear equation forms a line and a quadratic will appear as a parabola.
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.
There are linear functions and there are quadratic functions but I am not aware of a linear quadratic function. It probably comes from the people who worked on the circular square.
an equation has an equals sign.
They are continuous, differentiable functions.
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.

dunctions are not set equal to a value
linear
Both are polynomials. They are continuous and are differentiable.
The derivative of a quadratic function is always linear (e.g. the rate of change of a quadratic increases or decreases linearly).
