Imagine the graph
Sketch what it would look like.
What do you have to change in the equation y = sin x to move the graph up one unit? Write the new equation.
In the general equation
k, which parameter moves this graph vertically?
What are the intercepts of your new equation? Label them with their coordinates on the graph.
When you listed intercepts in part (c), did you list more than one x-intercept? Should you have?
See part (c). At what interval are the x-intercepts located?
