Effects of Constants on Exponential Functions

The video tutorial covers transforming exponential functions, focusing on vertical and horizontal shifts. It begins with graphing the parent function y = 3^x and then explores how adding or subtracting constants affects the graph's position. Vertical shifts occur when constants are added or subtracted at the end of the function, moving the graph up or down. Horizontal shifts happen when constants are added or subtracted in the exponent, moving the graph left or right. The tutorial emphasizes understanding these transformations and applying them to various functions.
