Question

Medal and fan!!!!

Answer 1

Use the quadratic equation y = x2 + 3x – 10.

Where does the vertex of the parabola lie?

below the x-axis
above the x-axis
on the x-axis
on the y-axis

Answer 2

the x2 should be x^2

Answer 3

FIRST AND FOREMOST, LILY: you do not need to tempt would-be helpers with this "medal and fan!!!!" stuff. It comes across as bribery.

Have you tried finding the coordinates of the vertex? Do you know the formula

x=-b/(2a)?

Find that x, then evaluate the function at that x value.
