Plz can somebody help me plz

Acircle has the equation (x-2)^2 +y^2 =5. what are the coordinates of the circle's center?

Asap describe the transformations required to obtain the graph of the function f(x) from the graph of the function g(x). f(x)=-5.8sin x. g(x)=sin x. a: vertical stretch by a factor of 5.8, reflection across y-axis. b: vertical stretch by a factor of 5.8,reflection across x-axis. c: horizontal stretch by a factor of 5.8, reflection across x-axis. d: horizontal stretch by a factor of 5.8 reflection across y-axis.

Graph y ≥ -x^2 - 1. click on the graph until the correct graph appears.
