SOLUTION: Without graphing, find the line of symmetry. The answer is either A,B,C,or D. I got Vertex: (-4,9) f(x) = -(x + 4)2 + 9 A)x = 9 B)x = 16 C)x = 5 D)x = -4

Question 209945: Without graphing, find the line of symmetry. The answer is either A,B,C,or D. I
got Vertex: (-4,9)
f(x) = -(x + 4)2 + 9

A)x = 9
B)x = 16
C)x = 5
D)x = -4

Since the line of symmetry passes thru the vertex
the line of symmetry must be x = -4
