Answer:
B
Step-by-step explanation:
We have that
<span>f(x)=2x</span>²<span>+12x+16
using a graph tool
see the attached figure</span>
Remember you can' do anything to boht sides, but when times negative, flip sign
distributive property
a(b+c)=ab+ac
distribute the -4
-8+4x
now we have
2x<8-8+4x
2x<4x
minus 2x both sides
0<2x
therefor
0<x
answer is x>0
The answer is c i’m pretty sure
