If the highest exponent of independent variable(say x) is 2 and the highest exponent of dependent variable(say y) is 1 and x and y are not multiplied, then the function is quadratic. For example:
3x-y+x2= 2y-5x+7 represents a quadratic function but y= xy+x2+5 doesn't represent a quadratic function.

What is thedifrent betweena quadratic equation and a quadratic function?
An equation just has an equal sign. A function is basically just an equation without one!
What is quadratic linear function?
It is a quadratic equation that normally has two solutions
Is the quadratic equation always a function?
Yes it is.
How do you determine if the graph of a quadratic function has a min or max from its equation?
If x2 is negative it will have a maximum value If x2 is positive it will have a minimum value
The difference between Quadratic function and quadratic equation?
dunctions are not set equal to a value
What is thedifrent betweena quadratic equation and a quadratic function?
An equation just has an equal sign. A function is basically just an equation without one!
What are the roots of the quadratic equation below?
That depends on the equation.
Why does the discriminant determine the number and type of the solutions for a quadratic equation?
A quadratic equation is wholly defined by its coefficients. The solutions or roots of the quadratic can, therefore, be determined by a function of these coefficients - and this function called the quadratic formula. Within this function, there is one part that specifically determines the number and types of solutions it is therefore called the discriminant: it discriminates between the different types of solutions.
What is quadratic linear function?
It is a quadratic equation that normally has two solutions
What is the axis of symmetry of a quadratic equation?
If a quadratic function has the points (-4,0) and (14,0), what is equation of the axis of symmetry?
What is the equation of the parent quadratic function?
x2
Is the quadratic equation always a function?
Yes it is.
How do you determine if the graph of a quadratic function has a min or max from its equation?

What is the relation quadratic equation to linear equation?
The derivative of a quadratic function is always linear (e.g. the rate of change of a quadratic increases or decreases linearly).
The difference between Quadratic function and quadratic equation?
dunctions are not set equal to a value
What do you find when you determine the discriminant?
Whether or not that there is a solution to a quadratic equation,
How aerospace engineers use the quadratic equation?
The quadratic equation is used to find the intercepts of a function (F(x)=x^(2*n), n being an even number) along its primary axis (typically the x axis). Many equations follow this form. The information given by the quadratic equation depends on what your function is pertaining to. If say you have a velocity vs time graph, when the function crosses the xaxis your particle has changed from a positive velocity to a negative velocity. This information can be useful to determine the accompanying behavior of your position. The quadratic equation is simply a tool to find intercepts of a function.
