Question

Which exponential function matches the table?

Answer 1

B: f(x) = 27
`((1)/(3))^(x)`

Explanation:

If you substitute 0 and 1 into each given exponential function. The first, second and fourth value with 0 substituted will give 27 as such, so we can eliminate the third exponential function. But, if you substitute 1 into all of the remaining possible exponential functions, the only function that will give you 9, when x = 1 is substituted, is B: f(x) = 27
`((1)/(3))^(x)`.

I hope this helps you!! ^-^
