Front

What is the elimination method in solving systems of equations?

Back

The elimination method involves adding or subtracting equations to eliminate one variable, making it easier to solve for the other variable.

Front

How do you determine what to multiply by in the elimination method?

Back

You multiply one or both equations by a number that will make the coefficients of one variable equal and opposite, allowing for elimination.

Front

What is the range of a function?

Back

The range of a function is the set of all possible output values (y-values) that the function can produce.

Front

How do you write the range of a function in interval notation?

Back

In interval notation, the range is expressed as a pair of numbers indicating the lowest and highest values, using brackets for inclusive and parentheses for exclusive.

Front

What does the domain of a function represent?

Back

The domain of a function represents the set of all possible input values (x-values) that the function can accept.

Back

In interval notation, the domain is expressed as a pair of numbers indicating the lowest and highest values, using brackets for inclusive and parentheses for exclusive.

Front

What is the solution to a system of equations?

Back

The solution to a system of equations is the point (or points) where the graphs of the equations intersect, representing the values of the variables that satisfy all equations.

Front

What does it mean for a function to be increasing?

Back

A function is increasing on an interval if, as the x-values increase, the y-values also increase.

Front

What does it mean for a function to be decreasing?

Back

A function is decreasing on an interval if, as the x-values increase, the y-values decrease.

Front

What is the significance of the y-intercept in a linear equation?

Back

The y-intercept is the point where the graph of the equation crosses the y-axis, representing the value of y when x=0.
