Question

Which line represents the axis of symmetry of the given graph?

A) y = 0
B) x = –1
C) x = 1
D) y = 2

Answer 1

C

Explanation:

the axis of symmetry is a vertical line passing through the vertex of the graph with equation

x = c ( c is the value of the x- coordinate of the vertex )

the coordinates of the vertex ( turning point ) are (1, - 9 )

with x- coordinate of 1 , then

equation of axis of symmetry is x = 1
