A power function raises the variable to a fixed power and scales it by a coefficient.
The math behind it
f(x) = a·xⁿ. Unlike an exponential function, here the variable is the base and the exponent is fixed.
Worked Example
f(x) = 2x³ at x = 4 → 2·64 = 128.Frequently Asked Questions
Power function vs exponential?
Power: variable base, fixed exponent (xⁿ). Exponential: fixed base, variable exponent (bˣ).
