Which of the following is/are not graph of a quadratic polynomial? (a) (b) A (c) (d)
Solution (a, b, c) (a) Since, the graph meets the x-axis in two distinct points A, B. :it is graph of a quadratic. (b) Since, the graph meets the x-axis in two distinct points A, B.it is graph of a quadratic. (c) Since, the graph meets the x-axis at the points A, B (distinct points) :: it is graph of a quadratic (d) Since, the graph meets the x-axis at a single point .. it is not graph of quadratic.
