## anonymous 4 years ago Which coefficient in the function tells us that the parabola for the function will point downward? y = -2x2 + 5x - 4

Coeffecient of x^2.

coefficient -2.....equation of any parabola is $a \times x^2+b \times x +c$ ...so when coefficient a >0 it goes upward, and if a <0 it goes downward...I hope I helped you, good luck :D
