Identify the Vertex, Axis of Symmetry, and Intercepts for the Graph

Question 81

Multiple Choice

Identify the vertex, axis of symmetry, and intercepts for the graph of the function.
- y=x2+8x+14y = x ^ { 2 } + 8 x + 14


A) Vertex at (4,2) ( - 4 , - 2 ) ; axis: y=2;xy = - 2 ; x -intercepts: none; yy -intercept: (42,0) ( - 4 - \sqrt { 2 } , 0 )
B) Vertex at (4,2) ( - 4 , - 2 ) ; axis: x=4;xx = - 4 ; x -intercepts: (42,0) ( - 4 - \sqrt { 2 } , 0 ) and (4+2,0) ;y( - 4 + \sqrt { 2 } , 0 ) ; y -intercept: (0,14) ( 0,14 )
C) Vertex at (4,62) ( 4,62 ) ; axis: x=4;xx = 4 ; x -intercepts: none; yy -intercept: (4+2,0) ( - 4 + \sqrt { 2 } , 0 )
D) Vertex at (4,62) ( 4,62 ) ; axis: y=62;xy = 62 ; x -intercepts: (42,0) ( - 4 - \sqrt { 2 } , 0 ) and (4+2,0) ;y( - 4 + \sqrt { 2 } , 0 ) ; y -intercept: (0,14) ( 0,14 )
