When the function f(x)=sinx is reflected across the y-axis, identify the coordinates of the reflected point of (π2,1) across the y-axis.(1 point) Responses (−π2,1) left parenthesis Start Fraction negative pi over 2 End Fraction comma 1 right parenthesis (π2,−1) left parenthesis Start Fraction pi over 2 End Fraction comma negative 1 right parenthesis (π2,1) left parenthesis Start Fraction pi over 2 End Fraction comma 1 right parenthesis (−π2,−1)
When reflecting a point across the y-axis, the x-coordinate remains the same but the y-coordinate changes sign.
The point (π/2, 1) reflected across the y-axis becomes (-π/2, 1).
So the correct answer is (−π/2, 1).
