Exponential model best represents the data is [tex]f(x)= 3(0.2)^{x}[/tex]
What is exponents?
A symbol written above and to the right of a mathematical expression to indicate the operation of raising to a power.
The given table values satisfied the fourth function.
If we put one by one all the values of x given in a table we get the corresponding value of f(x).
like, if we put -2 we get f(x)= 75 closer to 71
Hence, Exponential model best represents the data is [tex]f(x)= 3(0.2)^{x}[/tex]
