SP# 3: Unit I Concept 1: Graphing exponential functions and identifying x-intercept, y-intercept, asymptotes, domain, and range



The viewer needs to pay attention to certain points in order to fully understand this concept. For one, there can not be a x intercept if there is a negative because how can we take the natural log of a negative? Also, we must remember from previous chapters that x=0, and y=0, and we can find the x and y intercepts. Also, the domain will usually be all real numbers, meaning -infinity to +infinity. Lastly, we should remember that when looking for the asymptote, y=k. THANK YOU.
