Which of these cannot be a graph fir a quadratic equation |
|
Answer» Step-by-step explanation:(d) For any quadratic polynomial ax2 + bx + C, a≠0, the graph of the Corresponding equation y = ax2 + bx + c has ONE of the two shapes either open upwards like u or open downwards like ∩ depending on whether a > 0 or a < 0. These curves are called parabolas. So, option (d) cannot be possible.Also, the CURVE of a quadratic polynomial crosses the X-axis on at most two POINTS but in option (d) the curve crosses the X-axis on the three points, so it does not represent the quadratic polynomial. |
