The graph of a fraction-based function can have two types of breaks: a 'hole,' which is a single missing point, or a 'vertical asymptote,' which is a complete vertical line the graph can never cross.
The Factor Theorem creates a powerful link between a polynomial's graph and its equation: if a graph crosses the x-axis at a number 'k', you automatically know that '(x - k)' is a factor of the polynomial.
Logarithms possess a powerful property that allows them to transform complex multiplication problems into simple addition, and division problems into simple subtraction.
The powers of the imaginary number 'i' follow a simple, repeating four-step cycle: i, then -1, then negative i, and finally 1, before starting all over again.
The 'row-by-column' rule of matrix multiplication means that to find just a single entry in the new matrix, you must multiply an entire row from the first matrix with an entire column from the second.
