Let represent the number of years after 2013, hence in 2013 and in 2019,

Parent function:



We know that when , i.e. the year 2013, , therefore Billion.

And now we have



But when billion

So:









Do the arithmetic to calculate the value of which will allow you to express the desired function and, is coincidentally the answer to the last part of your question.
