Understanding Exponential Functions

Exponential functions are powerful tools for modeling situations with rapid growth or decay. The general form is $$f(x) = a \cdot b^x$$, where:

  • a is the coefficient, scaling the function vertically. It represents the initial value when x=0.
  • b is the base, determining the rate of change.
    • If b > 1, the function shows exponential growth.
    • If 0 < b < 1, it shows exponential decay.
  • x is the exponent, the variable in the function.

Use this calculator to explore how changing a, b, and x affects the function and its graph. Visualize the curve to understand exponential behavior.

Examples:

  • Population Growth: If a population grows at a rate of 5% per year, the growth can be modeled by an exponential function with b = 1.05.
  • Radioactive Decay: The decay of radioactive substances is modeled by exponential decay, where 'b' is less than 1.
  • Compound Interest: The amount of money after compound interest is calculated using an exponential function.
