Question

what are parabalas? Explain upwards and downward parabalas graphically.​

Answer 1

Answer:

Parabolas always have a lowest point (or a highest point, if the parabola is upside-down). This point, where the parabola changes direction, is called the "vertex". If the quadratic is written in the form y = a(x – h)2 + k, then the vertex is the point (h, k). This makes sense, if you think about it.

Answer 2

Answer:

hey there this is your answer...!!!

The graph of any quadratic equation y = a x 2 + b x + c , where a, b, and c are real numbers and a ≠ 0 , is called a parabola. ... Use the leading coefficient, a, to determine if a parabola opens upward or downward. If a is positive, then it opens upward. If a is negative, then it opens downward.
