Find the coordinate of the vertex on the parabola
State the answer in coordinate form.

(a)

If we have the equation y=ax²+bx+c, how can we can find the x-coordinate of the vertex?

• -a

• -b/a

• b/2a

• -b/2a

What is the vertex of y=x²+4x+3?

• (2,1)

• (-2,1)

• (0,0)

• (-2,-1)

• (5, -4)

• (-5, -4)

• (-15, -4)

• (15, -4)

• (-4, 1) 

• (-1, 4) 

• (4, -1) 

• (1, -4) 

Given the equation of the parabola, where would the VERTEX be? (put in standard form)

• ( 3 , 3)

• (24, 3)

• ( - 24, 3)

• (-3, 3)

Given the equation of the parabola, where would the VERTEX be?

• ( 3 , 3)
