Answer:
New function is:

Explanation:
Given:
The parent function given is:

Now, as per transformation rules, if a graph is vertically stretched by a factor of 'C' such that 'C' is greater than 1, then the function rule is given as:

So, we multiply the given function by 'C' units to get the transformed function.
Here,
and

As 3 > 1, therefore, the equation of the new function is given as:

Therefore, the equation of the new function is 3 times the original function and is equal to
.
