In which direction does the graph of (f(x)=-x^2) open?

Answer and explanation

Correct answer: Downward

The direct answer is option B: the parabola opens downward. For y=-x^2, x^2 is always non-negative, so -x^2 is always zero or negative. The vertex is (0,0), and points such as (1,-1) and (-1,-1) lie below the x-axis. Therefore the two arms go downward. Option B is correct. Option A would describe y=x^2, where the coefficient of x^2 is positive. Options C and D describe sideways parabolas such as x=y^2 or x=-y^2, not a graph written as y in terms of x with a squared x. Memory cue: in y=ax^2, a>0 means upward and a<0 means downward.
