Answer 2

Answer:

f(x) = $(\frac {1}{2})^{(6x)}$

Step-by-step explanation:

The given options are,

a) f(x) = $2^{(6x)}$

b) f(x) = $(\frac {1}{2})^{(6x)}$

c) f(x) = $2 \times (\frac {1}{6})^{x}$

d) f(x) = $\frac {1}{2} \times (\frac {1}{6})^{x}$

Now, clearly a) is a monotonically increasing function, hence discarded, and both of c)  and d) don't pass through (0, 1) hence they are also discarded.

Only b) is a decay function which does also pass through (0, 1), hence, b) is the correct option.
