Question
The graph of f(x) = - 11x2 _________.
Opens right side
Opens upward
Opens downward
Opens left side
The correct answer is: Opens downward
For a < 0, the parabola opens downward. f(x)= -11x2 is similar to the function f(x)= -ax2 for every value of x the value of f(x) will be negative. Hence , y coordinate is always negative and therefore the graph opens downward.
