Consider the function f(x) = 3 sin
– 4. Homework Help ✎
How is its graph different from the graph of g(x) = sin(x)?
Sketch the graph of y = f(x).
Look at the function's equation. What parts are different from the equation for g(x) = sin(x)?
How is the graph shifted horizontally? Vertically? How is it stretched?
Begin by drawing an axis that reflects the vertical shift. In this case it is y = −4.
