Question

Choose the function whose graph is given by: pic attached

Answer 1

looks like cosine, except the period is \(\pi\) instead of \(2\pi\) since the period is always \(\frac{2\pi}{b}\) set \(\frac{2\pi}{b}=\pi\) and solve for \(b\)

Answer 2

you get \(b=2\) in one step, making it the graph of \(\cos(2x)\)

Answer 3

right thank you
