x=5 could be an example of a(n) what?

• y-intercept

• x-intercept

• axis of symmetry

• vertex

Dude, what's the radical axis of symmetry for this gnarly equation?

y=x²+2x-1

• x= 1

• x= -1

• x= 2

• x= -2

Dude, where does this radical graph hit the y-axis?

• (-1, 0)

• (1, 0)

• (0, 1)

• (0, -1)

Dude, what's the radical axis of symmetry of this wicked graph?

• y= 0

• x= 0

• y= -1

• x= -1

What is the vertex of this graph?

• (2, 3)

• (1, 0)

• (-1, 0)

• (0, -1)

Dude, like, if Michelangelo was doing a rad skateboard trick on a half-pipe shaped like y=3x²+6x-12, at what point would he be at the very center of that gnarly curve?

• x= 1

• x= 2

• x= -2

Calculate the Vertex for the given equation:

y=x² - 6x + 4

• x= 3

• x= -3

• (3, -5)

• (-3, 31)

Dude, like, if Michelangelo was calculating the Axis of Symmetry for this gnarly equation:

y = 2x² + 12x + 2

What would it be?

• x = 6

• x = -6

• x = 3

• x = -3

Calculate the Vertex of the given equation:

y = 5x² - 10x + 15

• x = 1

• x = - 1

• (-1, 30)

• ( 1, 10)

What is the Vertex of this graph?

• ( 2, - 1 )
