Algebra 1 Vocab Review for Regents

Front

What is an Absolute Value Function?

Back

A function that describes the distance of a number from zero on the number line, represented as f(x) = |x|.

Front

What is a Quadratic Function?

Back

A function that can be expressed in the form f(x) = ax^2 + bx + c, where a ≠ 0.

Front

How can you identify a Linear Function from a table of values?

Back

If the y-values are increasing or decreasing by the same amount each time, the function is linear.

Front

What is an Arithmetic Sequence?

Back

A sequence of numbers in which the difference between consecutive terms is constant.

Front

What does it mean for a function to be Concave Up?

Back

A function is concave up if its graph opens upwards, indicating that the slope of the function is increasing.

Front

What is a Linear Function?

Back

A function that graphs to a straight line, represented in the form f(x) = mx + b.

Front

What is the standard form of a quadratic equation?

Back

The standard form is ax^2 + bx + c = 0, where a, b, and c are constants.

Front

What is the vertex of a parabola?

Back

The highest or lowest point of the parabola, depending on its orientation.

Front

What is the difference between a linear and a quadratic function?

Back

A linear function has a constant rate of change, while a quadratic function has a variable rate of change.

Front

What is the formula for 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.
