Vertex/Min/Max
Find the vertex and if there is a minimum or maximum point on the equation.
f(x) = -2(x-3)2 + 5
maximum (3,5)
The vertex of this equation y = 3(x-5)2+4
(5,4)
Find the axis of symmetry
f(x) = 4(x - 8)2 + 8
8
This variable in the vertex form equation for a parabola y = a(x-h)2+k tells you if the graph is narrow of wide
'a'
Find the vertex and if there is a minimum or maximum point on the equation.
f(x) = 2(x+3)2 + 10
minimum (-3,10)
The vertex of this equation y = 8(x+5)2+5
(-5,5)
Find the axis of symmetry
f(x) = 0(x + 17)2 + 18
-17
We know that a parabola opens downward if 'a' in the formula y=a(x-h)2+k is
What is negative
