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 does it mean for a function to have a domain of all real numbers?

Back

It means that the function can accept any real number as an input.

Front

How do you solve an equation for x?

Back

To solve an equation for x, isolate x on one side of the equation using algebraic operations.

Front

What is a quadratic function?

Back

A quadratic function is a polynomial function of degree 2, typically in the form y = ax^2 + bx + c.

Front

What does the graph of a quadratic function look like?

Back

The graph of a quadratic function is a parabola, which can open upwards or downwards depending on the sign of 'a'.

Front

What is the vertex of a parabola?

Back

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

How do you determine the number of outfits possible with different clothing items?

Back

Multiply the number of options for each clothing item together. For example, if you have 5 jeans, 8 t-shirts, and 2 shoes, the total outfits = 5 * 8 * 2 = 80.

Front

What is an extraneous root?

Back

An extraneous root is a solution that emerges from the process of solving an equation but does not satisfy the original equation.

Front

What is the standard form of a quadratic function?

Back

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

Front

What is the axis of symmetry in a quadratic function?

Back

The axis of symmetry is a vertical line that divides the parabola into two mirror-image halves, given by the formula x = -b/(2a).
