Answer:

  f^{-1}(x)=\pm\sqrt{x-10}

Step-by-step explanation:

You can find the inverse of

  y = f(x)

by solving for y:

  x = f(y)

__

  x = y² +10

  x -10 = y² . . . . . . . . subtract 10

  ±√(x -10) = y . . . . . take the square root

The inverse relation is ...

  \boxed{f^{-1}(x)=\pm\sqrt{x-10}}

__

It is not a <em>function</em> unless some restriction is placed on the domain of f(x).

Marissa dug three fifths of a hole in one tenth of an hour. Find the rate<br> in holes per hour
snow_lady [41]

Answer:

Step-by-step explanation:

This might be easier to do in decimals. Let's try it.

3/5 = 0.6

1/10 = 0.1

rate = holes / hours

rate = 0.6/0.1

rate = 6 holes per hour

Try it with fractions.

rate =       \frac{\frac{3}{5} }{\frac{1}{10} }    Invert and multiply the 1/10

rate =  \frac{3}{5} *\frac{10}{1} = 30/5 = 6

It's the same answer. Pick the method that you feel most comfortable with.
