Front

What is the range of a set of numbers?

Back

The range is the difference between the highest and lowest values in a set of numbers.

Front

How do you factor a trinomial of the form x^2 + bx + c?

Back

To factor a trinomial, find two numbers that multiply to c and add to b, then express it as (x + m)(x + n) where m and n are those two numbers.

Front

What is a linear regression equation?

Back

A linear regression equation models the relationship between two variables by fitting a linear equation to observed data.

Front

What does the vertex of a quadratic function represent?

Back

The vertex represents the maximum or minimum point of the parabola described by the quadratic function.

Front

How do you find the height of a projectile at a given time using a quadratic equation?

Back

Substitute the time value into the quadratic equation h(t) = -16t^2 + vt + h0, where v is the initial velocity and h0 is the initial height.

Front

What is the process to simplify an expression involving polynomials?

Back

Combine like terms by adding or subtracting coefficients of the same degree.

Front

What is the formula for the range of a set of scores?

Back

Range = Maximum score - Minimum score.

Front

How do you determine the factors of a quadratic equation?

Back

Use the quadratic formula or factor by grouping if applicable.

Front

What is the significance of the slope in a linear equation?

Back

The slope indicates the rate of change of the dependent variable with respect to the independent variable.

Front

What does it mean to simplify an algebraic expression?

Back

To simplify means to reduce the expression to its simplest form by combining like terms and eliminating unnecessary parentheses.
