Reciprocal Function: A mathematical function that gives the multiplicative inverse of another function. For example, if f(x) = 4/x, then its reciprocal would be g(x) = x/4.
Negative Exponent Rule: Involves taking the reciprocal (or flipping) of a base raised to a negative exponent. For example, 2^(-3) becomes 1/(2^(3)) = 1/8.
Reflection: In mathematics, reflection refers to flipping or reversing values across a certain axis or line.
