Question

What is the exponential function modeled by the following table?

x f(x)
2 10
3 28
4 82
A fx=2^x
B fx = 2^(x) +1
C fx=3^x
D fx= 3^(x)+1

Answer 1

`\bf \begin{array}{ccll} x&f(x)\\ \text{\textemdash\textemdash\textemdash}&\text{\textemdash\textemdash\textemdash}\\ 2&\stackrel{3^2+1}{10}\\ 3&\stackrel{3^3+1}{28}\\ 4&\stackrel{3^4+1}{82} \end{array}\implies f(x)=3^x+1`
