Sample question/s Unit Cram Sheet/Big Ideas Exponent Rules Watch out for fractional exponents they go to num and Den. Watch out for negative exponents only the base of the exponent moves-not the whole term! Equations with variables as a base Make each side have the same base set exponents equal to each other. Equations with variables as an exponent Raise each side by the reciprocal of the power of the variable. Exponential Functions 2. The number of bacteria in two A B, Exponential functions: colonies, and starts increasing at the The domain is always all real numbers or same time. The range is always restricted based off the horizontal asymptote The number of bacteria in The general exponential function , The y-intercept is (0,1) THINK TRANSFORMATIONS. colony A after t hours is modeled by the To sketch you MUST: 1. Give a point of reference( x intercepts or y interceps) function 2.Show asymptotes. Find the number of bacteria in colony A after four hours. Solving exponential functions: Substitute in values into function may need to use log rules to solve for exponent! How long does it take for the number of bacteria in colony A to reach 400?
