• a= 5
  b= 1
  c = 6

• a = 1
  b = -5
  c = -6

• a = 1
  b = 5
  c = -6

Multiple Choice

Given the standard form: $y\ =\ x^2+5x-6$    x = -b/2a What is the value of x?

• x= 5

• x = -5/2

• x = 5/2

Multiple Choice

Given the vertex (-2.5, -12.25) What is the vertex form of the equation?

Multiple Choice

Given the vertex form: $y\ =\ \left(x+3\right)\ ^2\ -5$   

What is the vertex

• (-3, 5)

• (3, 5)

• (-3, -5)

• (3, -5)

Open Ended

Given the standard form: $-x^2+2x+1$   

What is the vertex? 

 Hint: use the formula x = -b/2a, then substitute the x-value in to solve for y. Remember you write the vertex point (x, y).
