The equation that could be used to determine the total number of people is given as y is equal to 3^x.
<h3>What is an exponential function?</h3>It is defined as the function that rapidly increases and the value of the exponential function is always a positive. It denotes with exponent y = a^x
where a is a constant and a>1
Let y be the total number of people that will be tagged.
And let x be a number of the round.
We are assuming the first is when Kyla posted a photo challenge on social media and tagged 3 friends.
So from the problem the equation becomes:
At first round x = 1, y =3
At second round x = 2, y = 9
At third round x = 3, y = 27
Thus, the equation that could be used to determine the total number of people is given as y is equal to 3^x.
