If we had a graph of a half circle that is concave down in the first and second quadrant, what would the graph of the derivative look like? I'm having a hard time picturing it.

If the value of bo is negative, then the relationship: will not cause any impact to y values regardless of how the x values change. cannot be determined by this alone causes y to increase as x increases. causes y to decrease as x increases.

What happens to the curve on a graph for a function that has a negative phase shift and a negative vertical shift?

Please help with part D
