Logarithms and Exponential Functions
Algebra II Terms
Get down with the lingo
Exponential FunctionA function with the x in the exponent over a constant base, which grows or decays depending on the value of the base. Coefficient optional, like mayonnaise.
Inverse FunctionA function with switched input and output values from the original function. When graphed, it is a mirror image across both axes.
Inverse OperationA symbol that reverses the original operation, given the same input. Think about adding two then subtracting two.
Logarithmic FunctionA function containing a logarithm, which rises quickly at very low values of x and then puts on the brakes hard to slow down at higher values of x.
Logarithmic ScaleA graphing scale that increases at an exponential rate. It's usually recognizable by tick-marks at uneven intervals and weird googley eyes attached.
Natural LogarithmA logarithm with a base of e, often written as ln. Contains no preservatives.
OperationA way, usually represented by a symbol, to manipulate one or more input numbers and create one or more outputs. Not the board game, and definitely not surgery.
