The graphing of F(x) = cos (x) is transformed into a new function, g (x), by stretching it vertically by a factor of 3 and shifting it 2 units to the the left. What is the equation of the new function g(x) 

g(x) =

Becca do not post a lot of questions at once.

Post one or 2 at the most and learn from the answers that you get.

You can move it k units to the left (negative direction)  by replacing x with x+k

You can stretch it vertically  by  by multiplying the whole function (LHS) by a constant.

So what do you think the answer might be.

 

Here is the graph of      f(x) =cos x

You can add your new funtion onto it and see if it works.

Let me know what answer you get :)

 

 

Please no one answer over me - I am trying to teach.
