Required:
Equation of the new function.
Let the new function be represented by 
The interpretation of this question is that;

<em></em>
<em>Multiply 8 by x</em>

If

then

<em>Multiply 8 by x</em>

Recall that

<em>Substitute </em>
<em> in the above expression</em>

Hence, the equation of the new function when stretched by a factor of 8 is 
4.36 for number 8 and 9 is 6.19
Answer:
<h2>122.5</h2>
