Please help me with this

Polygons efgh and e′f′g′h′ are shown on the coordinate grid: what set of transformations is performed on efgh to form e′f′g′h′? a. a translation 1 unit to the left followed by a 90-degree counterclockwise rotation about the origin b. a translation 1 unit to the right followed by a 90-degree counterclockwise rotation about the origin c. a 90-degree clockwise rotation about the origin followed by a translation 2 units to the right d. a 90-degree clockwise rotation about the origin followed by a translation 2 units to the left

1-for what value of x is line a parallel to line b 2-for what value of x is line a parallel to line b

Which function is odd check all that apply a. y=sin x b. y=csc x c. y=cot x d. y=sec x
