Mercury’s average distance from the sun is 36 million miles. venus averages 67 1/2 million miles from the sun. how much greater is venus’ average distance from the sun than mercury?

31.5 miles.

Step-by-step explanation:

Mercury's average distance from the sun is 36 million miles.

Venus averages 67.5 million miles from the sun.

So Venus is 67.5 - 36 = 31.5 miles further from the sun than Mercury.

Step-by-step explanation:

f(x)=(8-x)²

let y=f(x)

flip x and y

x=f(y)

f^{-1}x=y

y=(8-x)²

flip x and y

x=(8-y)²

±√x=8-y

y=8±√x

\[f^{-1}(x)=8±√x\]

it is not a function.
