ANSWER

An exponential growth function.

The given function is

f(x) =  \frac{1}{2}  {(3})^{x}

This function is of the form,


f(x) = a {(b})^{kx}

umka2103 [35]

Answer:

n = 5, n = -7/2

Step-by-step explanation:

2n + 5 = l

n - 4 = w

A = l × w = 15

(2n + 5)(n-4) = 15

2n^2 - 8n + 5n - 20 = 15

2n^2 -3n - 35 = 0

(2n + 7)(n - 5) = 0

2n + 7 = 0      or       n - 5 = 0

n = -7/2          or       n = 5
