Question

PLEASE ANSWER RIGHT AEAY

Answer 1

`y=Sin(x-(\pi)/(4))`

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.

Note:

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

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

y = Sin (x-π/4)

The third answer choice is right.
