7. Below are graphs of combinations of two functions from $$x,x^2,\sin x,\cos x,2^x$$ and $$\log x$$ and one of the basic operations: addition, subtraction, multiplication and division. Determine an equation for each graph. Support your equation with a mathematical justification in part a) and 2 mathematical justifications in part b). Note that the graph in part b) will also contain a transformation.
