PLEASE ANSWER RIGHT AEAY
madam [21]

Answer:

y=Sin(x-\frac{\pi}{4})

Step-by-step explanation:

The basic graph of y = Sin(x), starts at x = 0.

Looking at the graph, the basic sin curve starts at x = π/4

So this function is the parent sin function shifted π/4 units to the right.

<u>Note:</u>

y = Sin(x-a)  is the parent function ( y= Sinx) shifted a units right

y = Sin(x+a)  is the parent function shifted a units left

<em>Since this function is shifted </em>π/4 units right, the equation would be:

y = Sin (x-π/4)

The third answer choice is right.
