**7.3 Logarithmic and Exponential Functions**Math 6B Calculus II**Exponential Functions**• The graph of y =bx, where b > 1 • The graph of y =bx, where 0 < b < 1**Inverse Relations for Exponential and Logarithmic Functions**• For any base b > 0, with , the following inverse relation hold. • Solving Logarithmic and Exponential Equations.**The Derivative of bx**• We will use logarithmic differentiation to find dy/dx where y = bx • The end resultwe get is:**Exponential Integral**• Exponential Integral of bx:**The Power Rule**• If n is any real number and f (x) = xn, then f ‘(x) = nxn-1
