Determine the values of
a, b, and c for
the quadratic equation: 
4x² – 8x = 3

• a = 4, b = -8, c = 3
• a = 4, b =-8, c =-3
• a = 4, b = 8, c = 3
• a = 4, b = 8, c = -3

Solve the equation by factoring:
x²-6x+8=0

• 2, 4
• -2, -4
• -2, 4
• 2, -4

find x for
x²+2x-8=0

• x= -4, 2
• x= -4, -2
• x= 4, 2
• x= -2, 4

If given the equation y = 3(x + 5)² - 4, what is the vertex of the parabola?

• (5, -4)
• (-5, -4)
• (-15, -4)
• (15, -4)

Which graph is a parabola?

• 
• 
• 
• 

Which equation would give the graph of a parabola?

• y = 2x - 3

• y = x₂ + 1

• y = x² + 4

Is the following parabola concave up or concave down?

• Concave down

• Concave up

• Neither

How can you tell whether a parabola is facing up or facing down by looking at the equation?

• The vertex tells you the direction of the opening
• The value of "a" tells you the direction of the opening.
• All parabolas open upward
• All parabolas open downward

What is the y-intercept of the parabola?

• -4

• 4

• -3

• 0
