System of linear equations
Multiply both equations by a suitable factor, then add the equations together to remove one unknown
What is the elimination method?
It associates elements of the domain to a single element of the codomain.
What is a function?
It is a two dimensional representation of all possible values of the function.
What is a graph?
Two terms connected by an equal sign.
What is an equation?
It can either be a arrow or a point.
What is the graphical reprsenation of a vector?
You isolate one variable in one equation and use it to replace the same variable in the other equation.
What is the Substituition method?
The intersection of a graph and the x-Axis.
What is a root?
It uses arrows to show the value of a function for depict values of the domain.
What is the mapping diagram?
It has a maximum of two solutions.
What is the toatal ammount of solutions of a quadratic equation?
You square both components, add them and calculate its square root.
What is a way to calculate the length of a vector?
You isolate one variable in one equation and use it to replace the same variable in the other equation.
What is the Substituition method?
A function with a constant product of both variables.
What is a indirect proportionality function?
There exists at least one x-value which is associated to two different y-values.
What does the graph of an invalid function look like?
It distinguishes between three possible solution cases.
What is the discriminant (D)?
You multiply both components of the vector with a real number.
How can you scale the length of a vector?
It is a empty set L={()}
What is the solution set of two distinct, parallel linear functions?
It shifts the graph of a function up- or downwards.
What is the influence of a constant number added to the function-equation on the graph?
The points of the first one can be connected, whereas the points of the second can't.
What is the difference between the graph of a real function and a discret function?
The Kleine Lösungsformel
Using this formula allows to solve a quadratic equation in the normalized represenation:
The result of the multiplication is zero
What is the vectorproduct of two orthogonal vectors?
