Question

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

y = 0.3^x


A: 0.9 B: 0.6 C: 0.06 D: 0.09

Answer 1

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

Explanation:

`\sf y = 0.3^x`

`\sf Plug \ x \ as \ 2.`

`\sf y = 0.3^2`

`\sf y =( (3)/(10) )^2`

`\sf y =(3^2 )/(10^2 )`

`\sf y =(9)/(100 )`

`\sf y =0.09`

Answer 2

The answer is d

Explanation:

0.09
