1) Graph of y= cos (x) is vertically stretched by the factor of 11, shifted the distance of 2 units to left, and translated 1 units downward.
Determine the formula for function whose graph is resulting graph
2) On graph of f(x)=6 sin(3Πx), points P and Q are at consecutive lowest and highest points with P occuring before Q. Determine slope of line that passes through P and Q.
