Algebra 2: Final Test Review

Front

What is a Square Root (Radical) Function?

Back

A function of the form f(x) = √x, where the output is the non-negative square root of x. It is defined for x ≥ 0.

Front

What is the first step in solving a system of equations using elimination?

Back

Identify and eliminate one variable by adding or subtracting the equations.

Front

Evaluate f(8) for f(x) = 3x - 2.

Back

f(8) = 3(8) - 2 = 24 - 2 = 22.

Front

What is the x-intercept of a function?

Back

The x-intercept is the point where the graph of the function crosses the x-axis, represented as (x, 0).

Front

What is the domain of a function?

Back

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

Front

What is a Quadratic Function?

Back

A function of the form f(x) = ax^2 + bx + c, where a, b, and c are constants and a ≠ 0.

Front

How do you find the vertex of a quadratic function?

Back

The vertex can be found using the formula x = -b/(2a) and then substituting x back into the function to find y.

Front

What is the difference between a function and a relation?

Back

A function is a specific type of relation where each input has exactly one output.

Front

What is the slope-intercept form of a linear equation?

Back

The slope-intercept form is given by y = mx + b, where m is the slope and b is the y-intercept.

Front

What does it mean for a function to be increasing?

Back

A function is increasing on an interval if, for any two points x1 and x2 in that interval, if x1 < x2, then f(x1) < f(x2).
