Graphs of Basic Exponential Functions • [7.1] PRE-CALCULUS 12

Want to learn about graphs of basic exponential functions? This video introduces this important family of functions graphically and numerically, and dynamically shows how the base affects the graphs and their features (general shape, domain & range, asymptotes, intercepts, end behaviour, etc.).
See the rest of my videos covering other Exponential Functions, Graphs, and Applications concepts:    • ★ Exponential & Logarithmic Functions...  
My instructional approach emphasizes conceptual understanding of and connections between concepts and ideas, rather than just pure memorization.

Corresponds to chapter 7, section 7.1 in McGraw-Hill's Pre-Calculus 12, but also fits with an exponents and logarithms unit from almost any other Pre-Calculus course or textbook.

A PDF copy of the 'Video Guide' document used in these videos as well as lots of other resources are available at https://drive.google.com/drive/folder...
