The graph of a quadratic function, y = x?, is reflected over the x-axis. Which of the following is the equation of the transformed graph?
O y=-x2
O y=(-x)2
Oy= v=x
Oy--

y = -x²

Step-by-step explanation:

When a parabola is reflected over the x-axis, it opens downward (unless it was already opening downward, in which case it would open upward after reflecting). When the "x²" term is negative, the parabola opens downward, so it's reflected over the x-axis. I hope this helps :))

by definition, an arc subtended by a central angle of some given measure has the same measure. so .

false

step-by-step explanation:

false.   two legs of the trapezoid would be congruent, but the other two would not.   were all the legs congruent, then we'd have a square; were the 2 shorter sides congruent and the 2 longer sides also congruent, we'd have a rectangle.
