Question

What is the value of y in this exponential decay function when x equals 2?

Answer 1

Answer:

The answer is d

Step-by-step explanation:

0.09

Answer 2

Answer:

$\boxed{\sf D. \ 0.09}$

Step-by-step explanation:

$\sf y = 0.3^x$

$\sf Plug \ x \ as \ 2.$

$\sf y = 0.3^2$

$\sf y =( \frac{3}{10} )^2$

$\sf y =\frac{3^2 }{10^2 }$

$\sf y =\frac{9}{100 }$

$\sf y =0.09$
