Question

Graph the equation . Which of the following
statements about the graph is correct? (1 point)
y = −5(x) + 1
2
The parabola will have a vertex at (1, 0).
The parabola will have a vertex at (−1, 0).
The parabola will have a vertex at (0, 0).
The parabola will open downwards.

Answer 1

Assuming the equation is y = −5x^2 + 1/2, the coefficient of x^2 is −5 (negative), so the parabola opens downwards. (Its vertex would be at (0, 1/2), so none of the listed point choices are correct.)
