AABC has coordinates A(-3, 1), B(1, 2) and C(-1,4). Write the coordinates of the image in matrix form.
a translation 1 unit right and 7 units up

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.

9/10 divide by -3/15 as a mixed number
