What is the inverse of the function? f(x)=3x−1

Hatshy [7]

Answer:

The inverse is 1/3 (x+1)

Step-by-step explanation:

y = 3x-1

Exchange x and y

x = 3y-1

Solve for y

Add 1 to each side

x+1 = 3y-1+1

x+1 = 3y

Divide each side by 3

(x+1)/3 = 3y/3

1/3(x+1) =y

The inverse is 1/3 (x+1)

strojnjashka [21]

Formula for volue of cylinder is area time height. Lets find area
A= $\pi r^2$
diameter=2r
8=2r
r=4
Now substitute r to $A= \pi r^2$
A= $\pi 4^2= 16\pi$
Now we have formula
V= $16 \pi *height=16 \pi *9=144 \pi$ - its the result, so B
