Answer:

umm i'm not rly sure what's going on here...but here's how i'd do it

Paul [167]

Answer:

Can someone help me with this f(g(x))=2(3x-4)^2+5?
Greeley [361]

Answer:

f(x)=349525

Step-by-step explanation:

f(x)=2(3x-4)^2+5

f(x)= 6x - 8^7

f(x)= 6x - 2,097,152

f(-6x)= - 2,097,152

/-6x       /-6x

f(x)=349525


I hope I am not terribly wrong but I probably am good luck
