Question

Write a function for which the new vertex that you found in 9 is a solution to the function, and allows the lizard to eat the mosquito.

  1. y = 2Ix – 100I    
  2. y = Ix – 100I    
  3. y = open vertical bar x over 100 close vertical bar    
  4. y = 2Ix + 100I    

hintHint:

First, we try to find out the equation by intuition. Then, we simply put in values of x's to validate it.

The correct answer is: y = 2Ix – 100I


    Step 1 of 1:
    This new function passes through (100, 0) and (200, 200)
    When the function shifts two blocks to the right horizontally, it becomes the following:
    y = 2Ix – 100I
    Putting x = 100, we get y = 0
    Putting x = 200, we get y = 2I200 – 100I = 200
    Putting x = 0, we get y = 200
    Final Answer:
    The right choice is-- D. y = 2Ix – 100I
