5 Questions
Which direction does a parabola open if the value of 'a' in the vertex form equation $y=a(x-h)²+k$ is positive?
Upward
What is the vertex of the parabola described by the equation $y=-10(x+4)²-3$?
(-4, -3)
What is the maximum or minimum point of a parabola if 'a' in the vertex form equation $y=a(x-h)²+k$ is negative?
Maximum point
If |a| > 1 in the vertex form equation $y=a(x-h)²+k$, how does the shape of the parabola compare to the graph of $y=x²$?
The parabola is 'skinny'
If |a| < 1 in the vertex form equation $y=a(x-h)²+k$, how does the shape of the parabola compare to the graph of $y=x²$?
The parabola is 'fat'
