Write f(x)= x2 + 4x -5 in vertex form.
f(x) = (x+2)2 - 5
f(x) = (x+2)2 - 9
f(x) = (x+4)2 - 9
f(x) = (x+4)2 - 5
What is the vertex of f(x) = (x + 4)2 - 5
(a)

Convert f(x) = x2 - 8x + 18 into vertex form.
f(x) = (x - 4)2 + 2
f(x) = (x - 8)2 + 10
f(x) = (x + 4)2 - 2
f(x) = (x + 8)2 -10
Convert f(x)= -3x2 - 12x -8 into vertex form.
State the vertex.
f(x) = -3(x + 2)2 - 4, Vertex ( -2, -4)
f(x) = -3(x - 6)2 + 4, Vertex ( 2, 4)
f(x) = (x + 6)2 + 4, Vertex ( -2, 4)
f(x) = -3(x + 2)2 + 4, Vertex ( -2, 4)
