Answer:
-16
Explanation:
Plug in -2 for x and then multiply 2 and 4 to get 8 (-2) which is then -16. Hope that helps!
The question asks to find x from 2(4)x if x = -2
All that we have to do is substitute to get our answer :
f(-2) for (x) = 2(4)x
f(-2) = 2(4)(-2)
f(-2) = 2(-8)
f(-2) = -16
Therefore, x = -16
