Will give brainloest if you answer both!

For the function, f(x) = -5x 2, find f(-4).

Brainlest answer can you find the area and circumference of a circle given the radius or diameter? if its yes or no explain why

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.
