-The vertex of a parabola is the highest or lowest point of the curve, sometimes called the maximum or minimum.
-The vertex is also the turning point of the parabola. -You can find the vertex by looking at the highest or lowest or turning point, you can also find it by finding the axis of symetry and pluging it into your x value to find the y value for the coordinates of the vertex, lastly you can find it by vertex form y= a(x-h)^2+k with the K and H values. |
-Zeros can have many names such as x intercept (s) or roots
-A function or parabola usually has 0, 1, or 2 zeros -To find the x intercepts you have to change y=0 and solve for x by using the qudratic formula or either, or statements -Example y= (x-s)(x-t) y= (x+2)(x-2) 0= (x+2)(x-2) 0= (x+2) or 0= (x-2) x= -2 or x= 2 |
-The axis of symetry of a parabola is a vertical line that devides the parabola into 2 congruent halves
-always passes through vertex of parabola -The equation of the axis of symetry is the x value of the vertex. For example, vertex= (0,0) axis of symetry = x=0 -You can also find the axis of symetry by finding out the midpoints of the zeroes |
