If f(x)=3x+6 what is the inverse of f(x)
Crank

Answer:

The inverse is 1/3x-2

Step-by-step explanation:

y = 3x+6

Exchange x and y

x = 3y+6

Solve for y

Subtract 6 from each side

x-6 = 3y+6-6

x-6 = 3y

Divide by 3

x/3 -6/3

1/3x -2 = y

The inverse is 1/3x-2

Part 3 <br>please help <br>​
aleksandr82 [10.1K]

I'm taking "part 3" to mean the 3rd of the posted questions.

If f(x)=(x^3+2x)\ln x, then

f'(x)=(x^3+2x)'\ln x+(x^3+2x)(\ln x)'=(3x^2+2)\ln x+\dfrac{x^3+2x}x

\implies f'(x)=(3x^2+2)\ln x+x^2+2

Then when x=1, we get f'(1)=3.
