Answer:
A vertical stretch by a factor of 3 and a shift up 2 units.
Step-by-step explanation:
To understand transformations of any function we have to learn what each number is doing to our base function. Constants that are added to the output of our base function shifts our function upwards and downwards. Numbers that are multiplied to the outputs of our base function stretch or shrink our functions vertically.
I would suggest watching multiple videos on transformations of graphs to get a better general understanding. If you would want a formula you would have to plot the points of the first function with any inputs and then plot the points of the same inputs with the new function.
