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.)

Ghella [55]

<u>Answer:</u>

The length of a paper clip chain is directly proportional to the number of paper clips. If a chain with 65 paper clips has a length of 97.5 inches then the length of chain with 14 paper clips is 21 inches.

<u>Solution:</u>

Given that the length of a paper clip chain is directly proportional to the number of paper clips. Directly propotional means when the length of paper clip increases, then the number of paper clips also increases in same ratio.

Hence, by above definition, we get  

\frac{l_{1}}{l_{2}} = \frac{n_{1}}{n_{2}}  ------- eqn 1

From question, for a chain with 65 paper clips has a length of 97.5 inches, we get  

l_{1} = 97.5 \text { and } n_{1} = 65

Similarly, for a chain with 14 paper clips with length to be found, we get  

n_{2}=14 \text { and } l_{2} = ?

Now by using eqn 1, we can calculate the length of 14 paper clips  is,

\frac{97.5}{65}=\frac{l_{2}}{14}

Rearranging the terms we get,

l_{2 }= \frac{97.5 \times 14}{65}

l_{2}=21 \text { inches }

Hence the length of chain with 14 paper clips is 21 inches.
