    Question

    For the following description, write a function in the form g(x) = aIxI. Vertex at (0, 0); passes through (1, 3)

    1. open parentheses 1 third close parenthesesIxI    
    2. 3IxI    
    3. 0.3IxI    
    4. IxI    

    hintHint:

    We simply plug in the values of x and validate the magnitude of the points. Furthermore, we equate the value of y with the given condition to find out the value of a and get the actual equation.

    The correct answer is: 3IxI

      Step 1 of 2:
      (0, 0): x = 0, g(x) = aI0I = 0
      Step 2 of 2:
      Now, (1, 3): x = 1, g(x) = aI1I = a
      Given, y = 3. So, a = 3.
      So, g(x) = 3IxI
      Final Answer:
      The right choice is-- D. 3IxI
