Front

What is the axis of symmetry in a parabola?

Back

The axis of symmetry is a vertical line that passes through the vertex of the parabola, dividing it into two mirror-image halves.

Front

Define range in the context of functions.

Back

The range is the set of all possible output values (y-values) that a function can produce based on its domain.

Which parent functions do not have a domain of all real numbers?

Back

Functions like square root functions and logarithmic functions do not have a domain of all real numbers.

Front

What is the definition of domain in functions?

Back

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

Front

Identify the parent function represented by the equation y = x².

Back

The parent function y = x² is a quadratic function, which produces a parabolic graph.

Front

What is a vertex in a parabola?

Back

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

Front

Explain the difference between domain and range.

Back

Domain refers to the set of input values (x-values), while range refers to the set of output values (y-values) of a function.

Front

What is a parent function?

Back

A parent function is the simplest form of a function type, from which more complex functions can be derived.

Front

How do you determine the vertex of a quadratic function in standard form?

Back

For a quadratic function in standard form y = ax² + bx + c, the vertex can be found using the formula x = -b/(2a).
