Ill give a brainliest the graph of g(x) is the graph of f(x)=12x+6 compressed vertically by a factor of 13 . which equation describes the function g? a) g(x)=12x+2 b) g(x)=4x+6 c) g(x)=36x+6 d)g(x)=4x+2

Guessing you meant by a factor of 3... not 13 since none of the solutions are anywhere close to that.

to compress is to smoosh.
It's the equation of a line. If you smoosh it vertically the line becomes flatter and the slope smaller. 

Essentially g(x) = 3f(x)
3y = 12x + 6
y = (12/3)x + 6/3
y = 4x + 2
