Find the inverse of the following function.
Naddik [55]

For this case we must find the inverse of the following function:

f (x) = 8 \sqrt {x}

For this, we follow the steps below:

We change f (x) to y:

y = 8 \sqrt {x}

We exchange the variables:

x = 8 \sqrt {y}

We solve for y:

8 \sqrt {y} = x

We divide between 8 on both sides of the equation:

\sqrt {y} = \frac {x} {8}

We raise both sides of the equation to the square to remove the root:

y = (\frac {x} {8}) ^ 2\\y = \frac {x ^ 2} {64}

So, the inverse is:f ^ {- 1} (x) = \frac {x ^ 2} {64}

8 miles is approximately equal to 6 km. How many km are equal to 28 miles? How many miles are equal to 42 km?
Pani-rosa [81]
1 mile = about 1  1/3 km because 8/6  = 1 1/3
so 28 times 1 1/3 = 37 1/3  (first answer)

42 / 6 = 7 
7 miles are in 42 km (2nd answer)
