Answer:
Choice A: stretched horoxontally by a factor of 2 and translated up by 3 units
Explanation:
The original graph is:
y = log(x)
The modified one is:
y = log(2x) + 3
We can note that 2 changes occured:
1- A 3 has beed added to the whole gaph. This means that the curve has been moved (translated) upwards by 3 units
2- The x inside the log is miltiplied by 2. This means that the graph is stretched horizontally by the factor added (2).
Combining these two, we will find that the correct choice is A
Hope this helps :)
