    Question

    Find the domain and range of the function.
    h(x) = 3.5IxI

    1. D: xless or equal than1/3.5, R: All real numbers    
    2. D: xless or equal than0, R: g(x) greater or equal than3.5    
    3. D: All real numbers, R: g(x) greater or equal than0    
    4. D: All real numbers, R: g(x)less or equal than5    

    hintHint:

    We simply plug in different values of x regardless of positive or negative and keep observing the values of y. Then, we conclude the domain as well as the range.

    The correct answer is: D: All real numbers, R: g(x) greater or equal than0

      Step 1 of 1:
      x = -2, h(x) = 7
      x = -1, h(x) = 3.5
      x = 0, h(x) = 0
      x = 1, h(x) = 3.5
      x = 2, h(x) = 7
      The value of x can be anything. So, the domain of h is all real numbers. And we can see the value of h(x) is always positive or zero. The range of h is h(x) greater or equal than 0.
      Final Answer:
      The right choice is-- C. D: All real numbers, R: h(x) greater or equal than0
