To determine the function
created from
by moving the graph left 2 units and vertically stretching it, we need to apply the given transformations to the original function.Step 1: Moving the graph left 2 unitsWhen a graph is moved left or right, it means that the x-coordinate of each point on the graph is shifted. In this case, the graph is moved left 2 units, which means that the x-coordinate of each point will be decreased by 2. Therefore, the new function after moving the graph left 2 units is:
Step 2: Vertically stretching the graphVertical stretching means that the y-coordinate of each point on the graph is multiplied by a certain factor. In this case, the factor is 3. Therefore, the new function after vertically stretching the graph is:
Therefore, the correct answer is C:
.
