Question 3
3.
Continuing with the transformation above, we have f(x)=-6x+2 and h(x)=f(\frac{1}{3}x)+4.
Changing the function f into the transformed function h requires both a horizontal stretch by a factor of 3 and vertical translation by 4 units.
Which of these two transformations affects the y-intercept, and how so? Explain your answer and add any equations or graphs necessary to make your explanation clear.

Question 6
6.
A spider produces silk for its web at a regular pace, so that the total linear length of silk in centimeters, f(x), is a function of how many hours the spider has been working, x.
When the spider is working normally, the function f is modeled by the equation f(x)= 75x.When the spider is forced to consume caffine, the quality of the web it weaves deteriorates. But the rate of silk production does increase, from 75 \frac{\textrm{cm}}{\textrm{hr}} to 100 \frac{\textrm{cm}}{\textrm{hr}}.
What type of transformation describes the change from normal silk production to accelarated silk production?
