Therefore: y = 3 x + 6 log 10 y = 3 log 10 x + 6 Using a x = y and log a y = x, we can change the '6' into a log. log 10 y = log 10 x 3 + log 10 10 6 log 10 y = log 10 10 6 x 3 y = 1000000 x 3 ...

Graphically, f (x) = x 2 is the same as the graph of y = x 2. Writing graphs as functions in the form of f (x) is useful when applying translations and reflections to graphs.
