Question

The parabola for the function will point in which direction? y = x2 + 3x - 4
Upward
Downward

Answer 1

A parabola opens upward if the coefficient on the x^2 term is positive. It opens downward if the coefficient on the x^2 term is negative. I'm not sure exactly what this question is asking for because it's worded ambiguously. What do they mean by "point," do they mean which way it opens? If so, your example opens up.

Answer 2

Upward because x^2 is positive.
