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)
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 should not be using this site to get you homework done for you.
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.
