PreCalculus - Exponential Function (3 of 13) Characteristics of Exponential Function 2

In this video I will explain the different characteristics of exponential functions of y=2^(x-1), y=-2^x, y=(2^x)+1...

Next video in the Exponential Function can be seen at:

immensely helpful, the way its presented, something never done when I was in school.

Thank you for the reply. It seems to me the function you are referring to in 3rd example should be written as y=-(2^x) since (ab)^x=(a^x)(b^x) implying -2^x = (-1^x)(2^x). Thanks for the great videos as they are great reviews!

In the second example if you put 0 in the x, 2^0-1 isn’t it equal to 0.5 how does it have a coordinate of (0, 1) ? Or does that belong to 2^x ?

in the 3rd example, -2^2=4 and not -4.
