Question

The graph of g(x) ​​is the graph of f(x)=12x+6 compressed vertically by a factor of ​1/3.


Which equation describes the function g?

​ g(x)=36x+6

​ g(x)=4x+6 ​

​ g(x)=12x+2

g(x)=4x+2

Answer 1

Vertically would mean in the y direction, so follow this rule :

Just multiply the function, f(x), by the constant

\(\large \color{red}{\frac{1}{3}} f(x) = \color{red}{\frac{1}{3}}(12x+6) \)

Answer 2

I think this would help you.

Answer 3

Your answer is D. G(x)=4x+2
