What is the value of x?

What is the vertex form of f(x) = x2 + 6x + 3

7(x - 2) = 3(x + 4) solve the following equation. then enter your answer in the space provided using mixed number format.

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.
