How do you find the nth term of an arithmetic sequence?

Back

The nth term can be found using the formula: \( a_n = a_1 + (n-1)d \), where \( a_1 \) is the first term and \( d \) is the common difference.

What does it mean for a function to be increasing?

Back

A function is increasing on an interval if, for any two points in that interval, the function value at the second point is greater than the function value at the first point.

Front

How can you determine the intervals where a function is increasing or decreasing?

Back

You can determine this by analyzing the derivative of the function; if the derivative is positive, the function is increasing, and if it is negative, the function is decreasing.

Front

What is a function?

Back

A function is a relation that assigns exactly one output for each input.

What is the vertical line test?

Back

The vertical line test is a method to determine if a curve is a graph of a function; if a vertical line intersects the curve at more than one point, it is not a function.

Front

What is the domain of a function?

Back

The domain of a function is the set of all possible input values (x-values) for which the function is defined.

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

What does it mean for a function to be decreasing?

Back

A function is decreasing on an interval if, for any two points in that interval, the function value at the second point is less than the function value at the first point.
