What does changing the a variable do to the graph of a quadratic?

I assume this question refers to the coefficient of the squared term in a quadratic and not a variable (as stated in the question). That is, it refers to the a in ax2 + bx + c where x is the variable.
When a is a very large positive number, the graph is a very narrow or steep-sided cup shape. As a become smaller, the graph gets wider until, when a equals zero (and the equation is no longer a quadratic) the graph is a horizontal line. Then as a becomes negative, the graph becomes cap shaped. As the magnitude of a increases, the sides of the graph become steeper.

How can you use a graph to find zeros of a quadratic function?
The zeros of a quadratic function, if they exist, are the values of the variable at which the graph crosses the horizontal axis.
The graph of a quadratic relation is a?
The graph of a quadratic relation is a parobolic.
What variable in a quadratic function causes the function to transform reflect or have a vertical stretch or shrink?
The wording is confusing, as a quadratic function is normally a function of one variable. If you mean the graph of y = f(x) where f is a quadratic function, then changes to the variable y will do some of those things. The transformation y --> -y will reflect the graph about the x-axis. The transformation y --> Ay (where A is real number) will cause the graph to stretch or shrink vertically. The transformation y --> y+A will translate it up or down.
Where On a line graph where is the dependent variable placed?
On a line graph, where is the dependent variable placed?
Does the graph of every quadratic function have a y-intercept?
Yes.
Where is break even on quadratic graph?
It depends on what variable is represented by the graph.

What shape does the quadratic graph make?
The graph of a quadratic equation has the shape of a parabola.
What are you finding when you solve a quadratic equation?
You are finding the roots or solutions. These are the values of the variable such that the quadratic equation is true. In graphical form, they are the values of the x-coordinates where the graph intersects the x-axis.
What is a parabola the graph of?
It is the graph of a quadratic equation of the formy = ax^2 + bx + c
What do you call the graph of a quadratic function?
the graph of a quadratic function is a parabola. hope this helps xP
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 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.
