Which graph decreases most rapidly from its vertex?

f(x) = 5x^2 – 3

f(x) = 3x^2 + 1

f(x) = –2x^2 – 3

f(x) = −3x^2 + 2.

Reason: a parabola's steepness is determined by |a| in ax^2+bx+c. Downward-opening (a<0) parabolas decrease from the vertex, and |−3|=3 > |−2|=2, so −3x^2+2 falls most rapidly.
