Question

Click on all that are true about the graph of y > x2 + 4x + 4.

1.The parabola opens up.
2.The line of symmetry is y = -2.
3.The vertex is at (-2, 0).
4.The parabola is dashed.
5.The parabola is shaded outside.

it could be more than one answer choice.

Answer 1

The sign of the coefficient of the x² term is positive, so the parabola opens upward. The line of symmetry is a vertical line, so it will be an x-value, not y. The vertex is (- 2, ) and the parabola is dashed and shaded inside.

Answer 2

so is the answer 4. the parabola is dashed
