1. a translation of function f is f1(x) = b(x – h). it is equivalent to a vertical stretch or vertical compression of function f. 2. the inverse of f1(x) = b(x – h) is equivalent to a translation of g. 3. the inverse of f1(x) = b(x – h) is not equivalent to a vertical stretch or vertical compression of g. 4. the function h(x) = logc x is a vertical stretch or compression of g or of its reflection –g. read this as “negative g”.
