  ↓               ↓                 ↓  

leave it   change it   turn it over

  \frac{2}{3}                ×                  \frac{5}{4}

now solve it

\frac{2}{3} × \frac{5}{4} = \frac{10}{12}

now simplify it

\frac{10}{12} = \frac{5}{6}

Answer:

  • left 3 units
  • up 4 units
  • shape: lower left image

Step-by-step explanation:

For a parent function f(x), the transformations ...

  g(x) = a×f(x -h) +k

cause ...

  • vertical expansion by 'a', reflection over x-axis if negative
  • right shift by 'h'
  • up shift by 'k'

Here, we have parent function f(x) = 1/x with a=-1, h=-3, k=4. Then the transformations are ...

  horizontal shift left 3 units

  vertical shift up 4 units

  reflection over x-axis, so curves are above-left and below-right of the reference point (Note that the reflection is done <em>before</em> the translation.)
