Question

which is the equation of the axis of symmetry of the graph of y = –3(x – 6)2 5? a.x = –6 b.x = –5 c.x = 5 d.x = 6

Answer 1

Hello,

y=-3(x-6)²+5
has x=6 like axis of symmetry.

Answer D

Answer 2

The answer is the option D

`x=6`

Explanation:

we have

`y=-3(x-6)^(2)+5`

This is a vertical parabola open downward

The axis of symmetry in a vertical parabola is equal to the x-coordinate of the vertex

The vertex is equal to the point
`(6,5)`

therefore

The equation of the axis of symmetry is

`x=6`
