The graph 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 left.

what is the equation of the new function g(x) ?

g(x) = 3 cos (x+2)

Step-by-step explanation:

To transform functions use the following formula f(x) = a cos b(x -c) + d where:

Here a = 3 and c = 2.

So the new function is g(x) = 3 cos (x+2).

Be careful with parenthesis
