Is it possible to write a cosine function for this graph?
Yes, it is.
If you think writing a cosine function is possible, write an equation that has cosine. If you think writing one is impossible, explain why.
The graph of
starts at a maximum. This graph has a maximum at Adlai says, “I can get that graph without shifting to the right or left.” What equation does he write?
