The cost of manufacturing x refrigerators is given by the function f(x)=2x^2+6000. if the cost doubles fr the year 2011 owing to higher raw material prices, which transformation will result in the graph of f(x)? choices: reflection, vertical stretch, vertical shrink, horizontal shrink, or horizontal stretch

 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 .  

7 ft 6 in means 7 1/2, because 6 in is 1/2 of a foot. 7 ft 8 in means 7 2/3 because 8 in is 2/3 of a foot. 23/3 = 7 2/3. 15/2 = 7 1/2.

23/3   *   15/2   = 57 1/2

step-by-step explanation:

6x = 48

i hope this . 6 cards each and a total of $48. dvide each side by 6 and you will have your answer.
