Question

F(-2) for f(x) =5•3^x

Answer 1

Explanation:

F(-2) for f(x) =5•3^x

Then, replace x by - 2

F(-2)=5•3^-2 (RULE= 3^-2 = 1/3^2)

`= 5. \frac{1}{ {3}^(2) }`

`= 5 . (1)/(9)`

`= (5)/(9)`

Hope this helps..have a great day!

Answer 2

5/9

Explanation:

f(x) =5•3^x

Let f = -2

f(2) =5•3^-2

= 5 * 1/ 3^2

= 5 * 1/9

= 5/9
