If ( f ∘ g)(x) = x2 - 6x + 8 and g(x) = x - 3, what is f(x)?
DochEvi [55]
\bf \begin{cases}
(f\circ g)(x)=x^2-6x+8\\\\
(f\circ g)(x)=f(~~g(x)~~)\\\\
g(x)=x-3\\
\end{cases}
\\\\\\
\textit{now, one probability is }x^2-1
\\\\\\
f(x)=x^2-1\implies f(~~g(x)~~)=(x-3)^2-1
\\\\\\
f(~~g(x)~~)=(x^2-6x+9)-1\implies f(~~g(x)~~)=x^2-6x+8

Will give brainliest to correct answer
Zigmanuir [339]

Answer: C - fog(2) = 1


Step-by-step explanation: x^3 and x-1 make x ^3-3x^2+3x-1.

Make those into a root by factoring the x^3 and 3x^2+3x-1

Cannot be simplified anymore so (x-1)(x^2-2x+1)

x^2 can be simplifed to make (x-1)(x-1)

So, you get (x-1)(x-1)(x-1).

Answer can be simplified to x=1 or fog(2) = 1

Hope you have the answer you are looking for and have a nice day!
