  1. Imagine the graph y = sin(x) shifted up 1 unit. Homework Help ✎

    1. Sketch what the graph would look like.

    2. What do you have to change in the equation y = sin(x) to shift the graph up 1 unit? Write the new equation.

    3. What are the intercepts of the graph of your transformed function? Label their coordinates on the graph.

    4. When you listed intercepts in part (c), did you list more than one x‑intercept? Should you have?

In the general equation y = sin (xh) + k, which parameter moves this graph vertically?

See part (c). At what interval are the x-intercepts located?
