📈 Exponential Function Calculator
📈 EXPONENTIAL FUNCTION FORMS
General Form: f(x) = a·b^x where b > 0, b ≠ 1
Natural Base: f(x) = a·e^(kx) where e ≈ 2.71828
Growth: b > 1 or k > 0
Decay: 0 < b < 1 or k < 0
📋 KEY FORMULAS
Doubling Time (growth): T₂ = ln(2)/k = log₂(b)
Half-Life (decay): T₁/₂ = ln(2)/|k| = log₀.₅(b)
Percent Change: r = b - 1 (or r = k for continuous)
Conversion: b = e^k or k = ln(b)
📈 EXPONENTIAL FUNCTIONS EXPLAINED
Exponential functions model rapid growth or decay. The variable x appears in the exponent, causing the function to increase or decrease by a constant multiplicative factor for each unit increase in x.
📋 HOW TO USE
1. Select function type (General or Natural base e).
2. Enter initial value (a) and growth factor (b) or rate (k).
3. Optionally enter specific x value to calculate f(x).
4. Click "Calculate" to see graph, properties, and value table.
⚠️ IMPORTANT CONSTRAINTS
Base b: Must be positive (b > 0) and not equal to 1.
Initial value a: Can be any real number (zero gives constant zero).
Growth vs Decay: b > 1 = growth; 0 < b < 1 = decay.
