How can you determine if a function is a quadratic function from its equation?
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.
When graphing an quadratic equation what two things do you have to use?
You have to use the independent and the dependent variable. Commonly, x and y are used for the variables, but could be a and b or any two symbols or characters.
What services as a standard of comparsion to evlauate the effect of the independent variable on a dependent variable?
It seems part of this question is missing. Perhaps the answer is that you might compare the effect to basic functions such as linear, quadratic, or exponential.
How is it called the relationship y equals x2?
It is a quadratic relationship which for every x, y is squared.
Is y equals 5x plus x squared a quadratic relationship?
Yes.
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 a quadratic relationship?
A quadratic relationship is a mathematical relationship that can be expressed by a quadratic formula in which the highest exponent is two (i.e., x squared). On a graph, this relationship will look like a parabola.

What is quadratic relationship?
y=x squared
What is the definition of a quadratic relationship?
something that has the same ralationship
Is the highest power of the independent variable in a quadratic function 2?
Yes.
How is it called the relationship y equals x2?
It is a quadratic relationship which for every x, y is squared.
What exists when one variable depends on the square of another?
Quadratic Relationship
Is y equals 5x plus x squared a quadratic relationship?
Yes.
What does a graph with a quadratic relationship look like?
Like a parabola. Not "like": it would be.
