What is the definition of a complex number?

Back

A complex number is a number that can be expressed in the form a + bi, where a and b are real numbers and i is the imaginary unit.

Front

What is the Quadratic Formula?

Back

x = (-b ± √(b² - 4ac)) / (2a)

Front

Define the term 'domain' in relation to functions.

Back

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

Front

Define the term 'range' in relation to functions.

Back

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

Front

What is the standard form of a quadratic equation?

Back

The standard form is ax² + bx + c = 0, where a, b, and c are constants.
