Write the equation for the parent linear value function, f(x)=x, that has been transformed by:

1. reflecting across the x-axis, vertical stretch by a scale factor 4, and a translation of 4 units up and 5 units left

2. vertical shrink by a scale factor of 1/4 and a horizontal shift 10 units right.

3. reflection in the x-axis, a vertical shift of 4 units up and a horizontal shift 7 units left
