Answer:

Hello,

Step-by-step explanation:

g(x)=2x+1\\(fog)(x)=f(g(x))=f(2x+1)=6x-2==3*(2x+1)\\\\f(2x+1)=3*(2x+1) \\or f(y)=3(y)\\or \boxed{f(x)=3x}\\

Answer:

g(x) = f(x) \\ 2x + 1 = 6x - 2 \\ 2x - 6x =  - 2 - 1 \\  - 4x =  - 3 \\ x =  \frac{3}{4}

I need help on a math problem<br> 48w^3+128w^2+4w-1<br> divided by<br> 4w
raketka [301]
Divide 4w to every term separately.

\sf\dfrac{48w^3+128w^2+4w-1}{4w}

\sf\dfrac{48w^3}{4w}+\dfrac{128w^2}{4w}+\dfrac{4w}{4w}-\dfrac{1}{4w}

48/4 = 12
w^3/w = w^2
So our first term is 12w^2.

128/4 = 32
w^2/w = w
So our second term is 32w.

4w/4w = 1
Anything divided by itself is 1.

-1/4w, this can't be simplified further, so this is our last term.

So we have:

\sf 12w^2+32w+1-\dfrac{1}{4w}
