What does the second power mean in math?
It is the square: the variable multiplied by itself.
What is the definition of quadratic eqau tion?
An equation where some variable is raised to the second power.
How do you know whether a relation is a function?
Use the definition of a function. If, for any value of one variable, there is only a single possible value of the second variable, then the second variable is a function of the first variable. The second variable is often called the "dependent variable". If you can solve an equation explicitly for the dependent variable, then it is a function. If you can NOT solve it for a variable, it may or may not be a function - it turns out that some equations are hard or impossible to solve explicitly for one of the variables.
Why are linear equations also called first-degree equation?
Equations can be classified according to the highest power of the variable. Since the highest power of the variable in a linear equation is one, it is also called a first-order equation.
What is it called when raising a number to the second power?
Taking a number to the second power is known as "squaring" the number.

What is the name for a polynomial equation containing a variable to the second power?
A quadratic equation.

An equation where some variable is raised to the second power.
What is an idea about what happens to one variable when a second variable changes?
An idea about what happens to one variable when a second variable changes is called correlation. Correlation measures the strength and direction of the relationship between two variables. It can help us understand how changes in one variable may be associated with changes in another variable.

What is the degree of this polynomial 3x to the 2nd power - 4x plus 9?
The highest power of the variable is 2, so it is a second degree polynomial.
What is it called when raising a number to the second power?
Taking a number to the second power is known as "squaring" the number.
In algebra I what is the input variable called?
The input variable is called the independent variable, and the ouput variable is called the dependent variable.
What is the input variable called in algebra?
the input variable is called the independent variable and the output variable is called the dependent variable.
Terms that contain the same variable with corresponding variables raised to the same power?
Terms that contain the same variable is called "like terms".
The input variable is called the what variable?
The independent variable. The output variable is dependent on this variable's value and so is called the dependent variable.
