The graph of y=sinx is reflected on the line x=y then on y=2 the resulting graph has which equation

y = 4 - sin⁻¹x

Step-by-step explanation:

1. Reflection about y = x

If we reflect a function ƒ(x) about the line y = x, we are creating its inverse, ƒ'(x).

Thus, reflection of y = sinx  about y = x gives y = sin⁻¹x.

The range of the reflection extends from -∞ to +∞, but the range of the function y = sin⁻¹x is [-π/2, π/2] (see Fig. 1) .

2. Reflection about y = 2

Reflection about y = 2 retains the sign of x but changes the sign of y.

Note, however, that in Figure 2 the point at (0, 0) is reflected to (4, 0).

The function is translated up by four units.

After the two reflections, the equation of the line is

y = 4 - sin⁻¹x

idk man good luck man
