Question

PLEASE HELP! find f(-2) for f(x) = 2x^x

Answer 1

B.
`(2)/(9)`

Explanation:

We need to find
`f(-2)` for
`f(x)=2*3^x`

To do this, we need to replace each instance of x in the equation with -2

`f(x)=2*3^x\\\\f(-2)=2*3^(-2)`

Now, we can remove the negative exponent by rewriting the equation

`f(-2)=2*(1)/(3^2)`

And now we can simplify

`f(-2)=2*(1)/(9)\\ \\f(-2)=(2)/(9)`

Answer 2

B .
`(2)/(9)`

Explanation:

`3^(-2) =0.1111\\`

2 x 0.1111 = .2222

`(2)/(9) = 0.2222`
