The square of thrice a number a, take away double a second number b

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.

The larger of two number is 4 less than twice the smaller number. the sum is 41. find the numbers

Write the sine and cosine values of a, b, respectively, in the figure for (1) and (2) + explanation.
