Gina pumps 40 cubic inches of air per second into a balloon. the function below shows the total amount of air f(t) inside the balloon after t seconds. f(w) = 40t + 5 which statement best describes the y-intercept of the graph of the function?

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.
