Understanding Exponential Functions
Exponential functions are mathematical expressions in which a constant base is raised to a variable exponent. The general form of an exponential function can be expressed as:
\[ y = a \cdot b^x \]
Where:
- \( y \) is the output value.
- \( a \) is a constant that affects the vertical stretch or compression.
- \( b \) is the base of the exponential function, and it must be a positive real number.
- \( x \) is the exponent, which is the variable.
Key Characteristics of Exponential Functions
1. Growth and Decay:
- If \( b > 1 \), the function represents exponential growth.
- If \( 0 < b < 1 \), the function represents exponential decay.
2. Intercepts:
- The y-intercept occurs at \( (0, a) \).
- Exponential functions do not have x-intercepts unless \( a = 0 \).
3. Asymptotes:
- Exponential functions have a horizontal asymptote, typically the x-axis (y = 0).
4. Domain and Range:
- The domain of exponential functions is all real numbers.
- The range is \( (0, \infty) \) for growth functions and \( (-\infty, 0) \) for decay functions.
