The function shown in the graph is vertically stretched by a factor of 4 to produce a new graph. Which function represents the new graph?

The correct answer will be d. -4

Answers: the graph is translated down 1 unit and the domain and range of g(x) is the same as the domain and range of f(x).

Period is the time it takes for one “cycle” to complete. in the parent sine function, period is 2*pi since sin(0) = 0, sin(pi/2) = 1, sin(pi) = 0, sin(3pi/2) = -1, and sin(2pi) = 0. at that point, the sequence repeats itself. i’m not sure if your graph is similar to the sine function since you didn’t provide a picture, but you can find the period by looking at a graph.
