Question

F(-2) for f(x) =5•3^x

Answer 1

Step-by-step 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)

$= 5. \frac{1}{ {3}^{2} }$

$= 5 . \frac{1}{9}$

$= \frac{5}{9}$

Hope this helps..have a great day!

Answer 2

Answer:

5/9

Step-by-step explanation:

f(x) =5•3^x

Let f = -2

f(2) =5•3^-2

     = 5 * 1/ 3^2

     = 5 * 1/9

     = 5/9
