![]() ![]() ![]() Inverse FunctionsĪn inverse function means taking a function (such as an exponent) and doing the inverse of it. Multiplying something by itself twice (Y x Y x Y) is known as cubing something, or raising it to the third power. Multiplying a value by itself is known as “squaring” something, represented as Y^2 or Y to the second power. There are specific terms for exponents that multiply something by itself once and those that multiply something by itself twice. Remember that the term “raising to a power” just means multiplying a given variable by itself to the specified number of times. For instance, 4^4 means 4 to the fourth power, or 4 x 4 x 4 x 4. When we speak of something being to the “Nth power” (N standing in for any number), we mean that number/variable is being multiplied by itself that many times. ![]() Exponents are just shorthand/stand for the repeated multiplication of a variable by itself. ![]()
