Answer: Vertical Stretch
Step-by-step explanation:
Given: The cost of manufacturing x refrigerators is given by the function :
If the cost doubles fr the year 2011 owing to higher raw material prices, then we multiply the given function by 2, then we get a new function :
which represents a vertical stretch in the graph.
∵ 2 is a positive constant greater than 1 which is multiplied to the parent function f(x). So by the definition of vertical stretch the parent function will be vertically stretched .
Answer:
1. vertical translation (the point goes straight up)
2. P'(0,7) (the translation was up five units and over 1 unit)
3. f(-2)=2(-2)^2-4= (all y values are 4) (0,4)
f(0)=2(0)^2-4= (all y values are -4) (0,-4)
f(1)=2(1)^2-4= (all y values are -2) (0,-2)
Answer:
71° F
Step-by-step explanation:
Consider the rational part of f(t)
( divide numerator and denominator by t³
= 
As t → infinity then 
→ 0 , the expression simplifies to
= 
= 40
Thus after driving for a long time
f(t) = 31 + 40 = 71° F
20/70, or .2857%, because there are 70 prizes total and 20 cats
