ocr: The restriction on the base b in our definition is important, although many students overlook it. These - aresome exponential functions: f(x)=2X F0)-5(3) F(R)=-6(3)% etc. None of these is an exponential function: - - - F(x)=(-3) - - - - - - - - f(x)=1x - STOP! Ve - - - f(x)=0x Exponential and Logarithmic Functions
