Front

What happens to the graph of y = x^2 when you multiply x^2 by a negative number?

Back

The graph opens downward.

Front

How does the equation y = 5(x - 5)^2 + 3 affect the width of the graph compared to the parent function y = x^2?

Back

The graph narrows.

Front

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 imaginary unit 'i'?

Front

What is the standard form of a complex number?

Back

The standard form of a complex number is a + bi, where a is the real part and b is the imaginary part.
