Function notation is a precise language, and transformations let you predict a graph without plotting it.
About 3 minThe inverse undoes the function, and its graph is the mirror image in the line y = x.
About 3 minThe logarithm is the inverse of the exponential, which is why it solves for exponents.
About 3 minGrade 12 graph questions combine several functions and test interpretation more than plotting.
