Question

Plz help me with this

Answer 1

Answer:
`\bold{C)\quad y=2sin(x+(3\pi)/(4))}`

Explanation:

A sin graph is a cosine graph shifted to the left
`(\pi)/(2)` units.

`y=2cos(x + (\pi)/(4))\qquad \implies y=2sin(x+(\pi)/(4)+(\pi)/(2))\\\\\\.\qquad \qquad \qquad \qquad \quad \implies \large\boxed{y=2sin(x+(3\pi)/(4))}`
