Does point (2,2) lie on line 3x-y=4

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

For the following geometric sequence, find the recursive formula. {-80, 20, -5, } i need : ')

Check all that apply. f is a function. f is a one-to-one function. c is a function. c is a one-to-one function.
