    Question

    Match the function p(x) = 3x to the graph.

    hintHint:

    We will substitute the points on given graphs to find which graph represents the given function.

    The correct answer is:

      GIVEN-
      p(x) = 3x
      TO FIND-
      Graph of the given function.
      SOLUTION-
      Since we have a function representing exponent of 3, the solution of y-coordinate can never be negative because 3 raised to any power cannot be negative.
      Hence, options c & d are eliminated.
      For x = 1, p(x) = 31 = 3
      Hence, the graph of p(x) should have point (1,3) on it.
      Hence, option a is also eliminated as it does not have (1,3) on the graph.
      Hence, option b is the correct option.
      FINAL ANSWER-
      Option 'b' is the correct answer to the given question.
