• {5.2, 5.7, 6.1, 6.6, 7.2, 8.21, 10.2, 14.7}

• [0, Infinity)

• [5.2, 14.7]

• (-Infinity, 14.7]

Which function bests models the following data?

• y = 2(9)^x

• y = 18(2)^x

Write an equation for the table.

• $f\left(x\right)=-3x+4$

• $f\left(x\right)=3x-4$

• $f\left(x\right)=-3\cdot4^x$

• $f\left(x\right)=4\cdot-3^x$

What is the Exponential equation for the table?
