Question

Please help me :( I don’t understand at all :(

Answer 1

B) 1/16

Explanation:

It's a lot easier than it looks ...

Plug in -4 to the x in 2^x

so you must find 2 to the power of -4

2^-4= 1/16

Hope this helps!

Answer 2

1/16

Explanation:

f(x) = 2^x

Let x = -4

f(-4) = 2 ^ -4

We know that a^-b = 1/a^b

= 1/2^4

= 1/16
